Exhibit 5.3

	21 October 2015

To the addressees set out in Schedule 1 (collectively, the “Addressees”)

Private and Confidential

Dear Sirs

We have acted as special Irish counsel to AerCap Ireland Capital Limited (“AICL”) and AerCap Ireland Limited (“AIL”) (each a “Company” and together, the “Companies”) in connection with the provision of this opinion letter to you in relation to certain Irish law matters set out in this Opinion on the Documents as defined below.

1. Documents examined, interpretation

1.1 For the purposes of this opinion letter, we have examined copies of:

(a) the documents listed in Schedule 2 hereto, collectively the “Documents”; and

(b) the following additional documents (the “Additional Documents”):

(i) a Certificate of a director of each Company dated 21 October 2015 (the “Certificates”); and

(ii) the results of searches made by independent law searchers on our behalf at the Companies Registration Office, Dublin, the Petitions Section and Judgments Office of the Central Office of the Irish High Court on 21 October 2015 against the Companies (together the “Searches”),

we have assumed that no circumstances or events have occurred between the dates on which the Certificates and Searches were given or made (none having being brought to our attention) which would cause us to cease to rely on the Certificates

and Searches. We have not conducted searches in any Office of the Circuit Court notwithstanding that the Circuit Court has jurisdiction to appoint an examiner but in this regard we have relied on the representations contained in the Certificates of the Companies.

1.2 Scope of opinion

This opinion letter speaks only as of its date and is limited to the matters stated herein and does not extend, and is not to be read as extending by implication, to any other matters.

In particular:

(i) save as expressly stated herein, we express no opinion on the effect, validity, or enforceability of or the creation or effectiveness of any document;

(ii) we express no opinion on the contractual terms of any document other than by reference to the legal character thereof under the laws of Ireland;

(iii) we express no opinion as to the existence or validity of, or the title of any person to, any of the assets which are, or purport to be sold, transferred, exchanged, assigned or otherwise dealt with under the Documents or as to whether any assets are marketable and/or are capable of being so dealt with free of any equities or of any security rights or interests which may have been created in favour of any other person;

(iv) we have made no investigation of, and express no opinion on, the laws, or the effect on the Documents and the transactions contemplated thereby of the laws, of any country or jurisdiction other than Ireland, and this opinion is strictly limited to the laws of Ireland as in force on the date hereof and as currently applied by the courts (excluding any foreign law to which reference may be made under the rules of Irish private international law). We have assumed without investigation that, insofar as the laws of any jurisdiction other than Ireland are relevant, such laws do not prohibit and are not inconsistent with any of the obligations or rights expressed in the Documents or the transactions contemplated by the Documents;

(v) we express no views or opinions on matters relating to tax;

(vi) we express no views or opinions as to matters of fact; and

(vii) we have not for the purpose of this opinion letter examined any other drafts and/or copies of any contract, instrument or document entered into by or affecting the Companies or any other persons, or any corporate records of the Companies or any other person, except the Documents and the Additional Documents; and (except as expressly set out herein) we have not made any other enquiries or searches concerning the Companies or any other person for the purposes of this opinion letter.

1.3 This opinion letter is governed by, and is to be construed in accordance with the laws of Ireland as at the date hereof and is subject to the exclusive jurisdiction of the courts of

Ireland. Except as otherwise expressly stated herein, the opinions expressed herein are given on the basis of and subject to the foregoing and the matters set out in part 2 (Assumptions) and part 3 (Reservations and Qualifications).

We also consent to the reference to us under the caption “Legal Matters” in the Prospectus Supplement. In giving this consent, we do not admit that or express any views on whether we are within the category of persons whose consent is required under the Securities Act, or the rules and regulations of the SEC thereunder nor shall we incur any liability solely as a result of the public filing of this Opinion with the SEC. Except as provided in paragraphs 1.5 and 1.6 and in this paragraph, this opinion may not be (in whole or in part) used, copied, circulated or relied upon by any party or for any other purpose without our prior written consent.

We confirm that that the Statutory Declarations dated 16 April 2014, 12 September 2014 and 21 May 2015 were delivered to the Registrar of Companies within the statutorily prescribed period. We also confirm that the Director’s Declaration dated 18 September 2015 has been delivered to the Registrar of Companies within the statutorily prescribed period;

(aa) that the opinions and matters respectively sworn in each Statutory Declaration were when sworn and given, and now remain, true and accurate and complete and are not misleading or incorrect in any respect;

3. Reservations and qualifications

3.1 The opinions expressed in this opinion letter are subject to the following reservations and qualifications:

Documents

(a) Provisions in the Documents imposing additional obligations in the event of breach or default, or of payment or repayment being made other than on an agreed date, may be unenforceable to the extent that they are subsequently adjudicated to be penal in nature, but, the fact that any payment is held to be penal in nature would not, of itself, prejudice the legality or validity of any other provision contained in the Documents which does not provide for the making of such payment.

(b) Provisions in the Documents that calculations or certifications or acknowledgements are to be conclusive and binding will not necessarily prevent judicial enquiry by the Irish courts into the merits of any claim by a party claiming to be aggrieved by such calculations, certifications or acknowledgements; nor do such provisions exclude the possibility of such calculations, certifications or acknowledgements being amended by order of the Irish courts.

(c) To the extent that the Documents vest a discretion in any party, or provides for any party determining any matter in its opinion, the exercise of such discretion and the manner in which such opinion is formed and the grounds on which it is based may be the subject of a judicial enquiry and review by the Irish courts.

(d) The effectiveness of terms in the Documents exculpating a party from a liability or a legal duty otherwise owed are limited by law including insofar as the liability of trustees are concerned section 422 of the Companies Act 2014.

(e) Provisions of the Documents providing for severance of provisions due to illegality, invalidity or unenforceability thereof may not be effective, depending on the nature of the illegality, invalidity or unenforceability in question.

Enforceability/Binding Nature of Obligations

(f) The description of obligations as “enforceable” or “binding” refers to the legal character of the obligations in question. It implies no more than that they are of a character which Irish law recognises and enforces. It does not mean that the Documents will be binding or enforced in all circumstances or that any particular remedy will be available. Equitable remedies, such as specific performance and injunctive relief, are in the discretion of the Irish courts and may not be available to persons seeking to enforce provisions in the Documents. More generally, in any proceedings to enforce the provisions of the Documents, the Irish courts may require that the party seeking enforcement acts with reasonableness and good faith. Enforcement of the Documents may also be limited as a result of (i) the provisions of Irish law applicable to contracts held to have become frustrated by events happening after their execution and (ii) any breach of the terms of the Documents by the party seeking to enforce the same.

(g) Any person who is not a party to the Documents may not be able to enforce any provision thereof which is expressed to be for the benefit of that person.

(h) The obligations of each Company under the Documents are subject to all insolvency, bankruptcy, liquidation, reorganisation, moratorium, examinership, trust schemes, preferential creditors, fraudulent transfer and other similar laws relating to or affecting creditors’ rights generally.

(i) Where an obligation is to be performed outside Ireland under the Documents, it may not be enforceable in Ireland to the extent that performance would be illegal or contrary to public policy under the laws of that jurisdiction.

(j) Any judgment of the Irish courts for moneys due under the Documents may be expressed in a currency other than euro but the order may issue out of the Central Office of the High Court expressed in euro by reference to the official rate of exchange prevailing on or very shortly before the date of application for judgement. In addition, in a winding-up in Ireland of an Irish incorporated company, all foreign currency claims must be converted into euro for the purposes of proof. The rate of exchange to be used to convert foreign currency debts into euro for the purposes of proof in a winding-up is the spot rate as of, in the case of a compulsory winding-up either the date of commencement of the winding-up (presentation of the petition for winding-up or earlier resolution for winding-up) or of the winding-up order and in

the case of a voluntary winding-up on the date of the relevant winding-up resolution.

(k) An Irish court may refuse to give effect to a purported contractual obligation to pay costs arising from unsuccessful litigation brought against that party and may not award by way of costs all of the expenditure incurred by a successful litigator in proceedings before that court.

(l) Claims against a Company be or become the subject of set-off or counterclaim and any waiver of those or other defences available to such Company may not be enforceable in all circumstances.

(m) Currency indemnities contained in the Documents may not be enforceable in all circumstances.

Statutes of Limitation

(n) Claims against a Company may become barred under relevant statutes of limitation if not pursued within the time limited by such statutes.

Searches

(o) The failure of the Searches to reveal evidence that a Company has passed a voluntary winding-up resolution, that a petition has been presented or order made by a court for the winding-up of, or appointment of an examiner to a Company or a receiver or similar officer has been appointed in relation to any of its assets or revenues is not conclusive proof that no such event has occurred, in particular:

(i) the Searches may not have revealed whether a petition for winding-up or the appointment or any examiner had been presented;

(ii) notice of a resolution passed, a winding-up order made or the appointment of a receiver or examiner may not have been filed at the Irish Companies Office immediately;

(iii) it has been assumed that the information disclosed by the Searches was accurate and that no information had been delivered for registration that was not on the file at the time the Searches were made;

(iv) the position may have changed since the time the Searches were made; and

(v) searches have not been undertaken in any Office of the Circuit Court, notwithstanding that the Circuit Court has jurisdiction with respect to the examinership of certain companies.

Offer or Sale of Notes in Ireland

(p) The underwriting or placement of Notes in or involving Ireland by an Addressee or another person must be in conformity with the provisions of the Companies Act 2014 and the European Communities (Markets in Financial Instruments) Regulations 2007 (Nos.1 to 3) of Ireland including, without limitation, Regulations 7

and 152 thereof or any codes of conduct issued in connection therewith and the provisions of the Investor Compensation Act 1998.

(q) An offer of Notes to the public in Ireland or seeking their admission to trading on a regulated market situated or operating in Ireland by an Addressee or another person must be in conformity with the provisions of the Prospectus (Directive 2003/71/EC) Regulations 2005 of Ireland and any rules issued under Section 51 of the Investments Funds, Companies and Miscellaneous Provisions Act 2005 or, as applicable, section 1363 of the Companies Act 2014 by the Central Bank of Ireland.

(r) To the extent they may apply, underwriting, placing or otherwise acting in Ireland in respect of the Notes by an Addressee or another person must be in conformity with the provisions of the Market Abuse (Directive 2003/6/EC) Regulations 2005 of Ireland and any rules issued under Section 34 of the Investment Funds, Companies and Miscellaneous Provisions Act 2005 or, as applicable, section 1370 of the Companies Act 2014 by the Central Bank of Ireland, the Companies Act 2014, the Central Bank Acts 1942 to 2015 and any codes of conduct rules made under Section 117 (1) of the Central Bank Act 1989.

4. Opinion

Other than as described in Section 1 above, under the assumptions set out at Section 2 above and the reservations set out in Section 3 above and to any matters or documents not disclosed to us, we are of the opinion as follows:

4.1 Due Incorporation

Each Company is duly incorporated and validly existing under the laws of Ireland as a private limited company and the Searches revealed no order, resolution or petition for the winding-up of or for the appointment of an examiner over any Company and no notice of appointment of a liquidator, receiver or examiner in respect of any Company

4.2 Corporate Capacity

(a) Each Company has the necessary legal capacity and authority to enter into, deliver and perform its obligations under the Documents to which it is a party;

(b) AICL has the necessary legal capacity and authority to issue, enter into, deliver and perform its obligations under the Notes;

4.3 Corporate Authorisation

(a) All necessary corporate action has been taken by each Company to authorise the entry into, execution and performance of the Documents to which it is a party;

(b) All necessary corporate action has been taken by AICL to authorise the issuance of, entry into, execution of and performance under the Notes;

(c) All necessary corporate action has been taken by AIL to authorise the granting of and performance under the Guarantees.

4.4 Due Execution

The Documents to which it is a party have been duly executed by each Company.

Yours faithfully
