Dear Sirs and Mesdames

CHC Helicopter Corporation ("CHC")

Opinion as to Scots Law

1    Introduction

    We act as legal advisers in Scotland to certain subsidiaries of CHC.

    The Registration Statement relates to the offer by CHC to exchange (the "Exchange Offer") CHC's outstanding unregistered US$250,000,000.00 aggregate principal amount of 73/8% Senior Subordinated Notes due 2014 (the "Outstanding Notes") for CHC's US$250,000,000 principal amount of 73/8% Senior Subordinated Exchange Notes due 2014 (the "Exchange Notes") that will be registered under the Securities Act, as set out in the prospectus forming a part of the Registration Statement (the "Prospectus").

    We understand that the Exchange Notes will be issued under the Indenture (as hereinafter defined).

4    Opinions

    Based upon the foregoing assumptions and subject to any matters not disclosed to us we are of the opinion that, so far as the present law of Scotland is concerned, and subject to the qualifications and reservations set out below:-

5


    4.1
    Each Scottish Subsidiary Guarantor has the corporate power and capacity to execute and perform its obligations under, and each has duly executed, authorised and delivered, the Indenture.

    4.2
    The Indenture constitutes the valid and legally binding obligations of each Scottish Subsidiary Guarantor.

5    Qualifications and Reservations

    Notwithstanding the foregoing, the opinions expressed in this letter are subject to the following qualifications and reservations:-

5.1
Insolvency etc.: our opinions are subject to all limitations and modifications of rights and obligations resulting from the law of bankruptcy, liquidation, receivership, reorganisation, reconstruction, moratoria, court schemes, insolvency, administration and other laws generally affecting the rights of creditors or from any other laws or principles of natural justice or public policy.

5.2
Valid and Legally Binding: the expression "valid and legally binding" does not mean that the obligations referred to will necessarily be enforced in all circumstances in accordance with their terms, as to which reference is made to the other qualifications and reservations herein expressed.

5.3
Lawful Performance: our opinion in paragraph 4.2, assumes that the Scottish Subsidiary Guarantors will perform their respective obligations under the Indenture out in accordance with the terms of the Indenture and that such performance will in all respects be lawful.

5.4
Foreign Judgements: enforcement in Scotland of any document expressed to be governed by a law other than Scots law requires either (i) enforcement of a judgement of the courts of the proper law under the procedures set out in the Civil Jurisdiction and Judgements Act 1982 (as amended) (the "1982 Act") and applicable subordinate legislation or rules of court or (ii) if the 1982 Act does not apply, enforcement of such a judgement through an action of decree conform, under common law in the Court of Session in Scotland. A judgement of a US Court is enforced in Scotland by raising an action for decree conform to the decree of the US Court. The action must be raised in the Court of Session in Edinburgh. In effect therefore, a US judgement cannot be enforced in Scotland without the institution of fresh legal proceedings. Certain conditions relating to the US judgement must be met before it will be enforceable in Scotland, as follows:-

5.4.1
the US judgement must have been granted by a superior court in the US;

5.4.2
the defender must be subject to the jurisdiction of the court where the decree is to be enforced (i.e., the Court of Session) (and we can confirm that the Scottish Subsidiary Guarantors would be so subject);

5.4.3
the US court must have had jurisdiction in the international sense (i.e., the foreign court must have been entitled to summon the defender and subject him to judgement);

5.4.4
the US judgement must be final and must be res judicata in the law of the state where it was given;

5.4.5
the US judgement must be for a fixed sum; and

5.4.6
the US judgement must not relate to penal or revenue laws.

      Where an action for decree conform is raised, the action may be challenged on the ground that any of the above conditions are not met. In addition, the Court of Session will not investigate the propriety of the proceedings in the US court (other than in relation to

6


      jurisdiction) and it will not sit as an appeal court against a judgement of a US Court which was competent to exercise jurisdiction over the parties in the case.

      The following additional defences are available to an action for decree conform:-

    5.4.7
    the US judgement was obtained by fraud;

    5.4.8
    the US judgement is contrary to public policy in Scotland;

    5.4.9
    the US judgement is contrary to natural justice;

    5.4.10
    judgement in the US court was taken contrary to an agreement relating to the settlement of the dispute (for example where there is an arbitration agreement in force);

    5.4.11
    there has been a prior Scottish judgement in respect of the same matter;

    5.4.12
    the US judgement is no longer extant (e.g., where it is time-barred under the US legal system or where it has been satisfied);

    5.4.13
    the US court did not act judicially or there was some irregularity in the US proceedings.

5.5
Remedies: certain remedies, such as an order for specific implement or the grant of an interdict or interim interdict may be available only at the discretion of the court. A court will not grant specific implement in respect of an obligation to pay money or, where implement is impossible, may refuse the remedy on equitable and public policy grounds. No opinion is therefore expressed on whether any specific remedy, other than monetary damages, would be available.

5.6
Foreign Terms: insofar as the Indenture makes reference to or adopts definitions or interpretations from legislative or common law provisions which apply in any jurisdiction other than Scotland no opinion is given as to the relevant provisions of the document incorporating such definitions or interpretations of the import thereof.

5.7
Penalties: any provision for additional interest to be paid on overdue amounts may amount to an irrecoverable penalty. In addition, an obligation to pay a contractual rate of interest may be superseded by a judgement of a Scottish court.

5.8
Currency Indemnity: a Scottish court may not give effect to any form of currency indemnity.

5.9
Litigation Costs Indemnities: the Scottish courts will not necessarily give full effect to an indemnity for the costs of litigation.

5.10
Severance Clauses: severability clauses may not be binding under the law of Scotland and a Scottish court would determine at its discretion whether invalid or unlawful provisions of a document may be severed from the other provisions of that document.

5.11
Procurement Obligations: the enforceability of any provision in any documents providing that any party shall procure the performance of any obligation(s) by another company which is not a party to the relevant document is subject always to the fiduciary duties of the directors of that other company.

5.12
Obligations to be Performed outside Scotland: where any obligation is to be performed or observed in a jurisdiction outside Scotland it may not be enforceable under Scots law to the extent that such performance would be unlawful, illegal or unenforceable or contrary to public policy under the laws of any such jurisdiction.

5.13
Foreign Currencies: whereas a Scottish court may be prepared to render a judgement for a monetary amount in a foreign currency, for enforcement purposes that may require to be converted to Sterling. Amounts claimed in a Scottish liquidation must be converted to Sterling at the rate prevailing at the commencement of liquidation.

7


5.14
Law of Scotland Only: we have not investigated the laws of any jurisdiction other than Scotland and this opinion is given only with respect to the law of Scotland as in force and as interpreted by the Scottish courts as of the date of this letter. Without limitation to the foregoing:-

5.14.1
we express no opinion on any aspect of the Securities Act or any other law of the United States of America;

5.14.2
we do not, by giving the consent to registration referred to below, or otherwise, represent or imply or concede that we are within the category of persons whose consent for such registration is required by the Securities Act or the General Rules and Regulations promulgated under the Securities Act;

5.14.3
we do not, by giving the opinions set out in this letter or the consent to registration referred to below, or otherwise, represent or imply or concede that we are "experts" in relation to any matter relating to the Indenture, the Outstanding Notes, the Exchange Notes, the Exchange Offer, or the Registration Statement.

    This opinion letter is addressed to Messrs Shearman & Sterling LLP and CHC Helicopter Corporation and is solely intended for their benefit in connection with the registration of the Registration Statement. We consent to the filing of this opinion letter as Exhibit 5.3 to the Registration Statement.

    Save as expressly provided above, this opinion letter is not to be relied upon by any other person or for any other purpose nor be quoted, referred to or made public in any way, nor filed with any government agency or other person without our prior written consent. Any communication or disclosure given with our consent must be given subject to the condition of excluding any reliance on the terms thereof whether or not such condition is specified by us at the time of giving such consent.

    This opinion letter is given on the condition that it shall be governed by and construed in accordance with the law of Scotland and that any action arising out of it is subject to the exclusive jurisdiction of the Court of Session in Scotland.

Yours faithfully


/s/  
Paull & Williamsons
