21 July 2004

To:

CHC Helicopter Corporation,
Hangar No. 1, St. John's Airport,
P. O. Box 5188,
St. John's, NL A1C 5V5

Shearman & Sterling LLP

Dear Sirs

CHC Helicopter Corporation (the "Company")
Exchange Offer of U.S.$250,000,000
7³/8% Senior Subordinated Notes due 2014

1.

We have acted as English legal advisers to the Company and CHC Scotia Limited, North Denes Aerodrome Limited and Management Aviation Limited (the "English Guarantors") in connection with the preparation and filing with the U.S. Securities and Exchange Commission under the U.S. Securities Act of 1933, as amended (the "Securities Act') of a Registration Statement on form F-4 (the "Registration Statement").

2.

The Registration Statement relates to the offer by the Company to exchange (the "Exchange Offer") the Company's outstanding unregistered US$250,000,000.00 aggregate principal amount of 7³/8% Senior Subordinated Notes due 2014 (the "Outstanding Notes") for the Company'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.

3.

The Exchange Notes will be issued under the indenture dated as of 27 April 2004 among the Company, the Guarantors (as such term is defined in the Indenture) and The Bank of New York as Trustee, (the "Indenture").

4.

We have examined copies of the following documents:

(a)

the Indenture (including the Guarantees);



(b)

the Outstanding Notes;



(c)

the form of the Exchange Notes;



(d)

a certified copy of the Memorandum and Articles of Association of each of the English Guarantors; and



(e)

a certified copy of the minutes of the meeting of the board of directors of each English Guarantor held on 20 April 2004 at which a resolution was passed approving the transactions contemplated by the Indenture, the Registration Rights Agreement (as defined in the Indenture) and approving the terms and authorising the execution of such documents to which it is a party.

        The resolutions referred to in paragraph 4 (e) above are referred to in this opinion as the "Resolutions."

        On 21 July 2004 we carried out a full search of the Companies House online database in respect of each English Guarantor. At 4.30 p.m. today, we carried out a search of the filing history page of the Companies House online database in respect of each English Guarantor. At 4.30 a.m. today we made a telephone enquiry of the Central Index section for Company Searches and Winding Up Petitions in relation to each English Guarantor. The searches and enquiries referred to above revealed that no

order, petition or resolution for winding up, no interim or final administration order, no intention to appoint an administrator and no notice of the appointment of a receiver, administrative receiver or administrator, had been filed at that time with respect to the English Guarantors.

        Terms and expressions which are defined in the Registration Statement have the same respective meanings where used in this letter.

        This opinion is confined to matters of English law as applied by the English courts on the date hereof. We express no opinion on any other system of law. In particular, we express no opinion on European Community law as it affects any jurisdiction other than England. To the extent that the laws of any other jurisdiction may be relevant, we have made no independent investigation thereof.

        On the assumptions set out in Appendix A and subject to the qualifications set out in Appendix B, we are of the opinion that:

1.

Each of the English Guarantors is a company incorporated with limited liability under the laws of England and Wales with the corporate power to enter into and perform its obligations under the Indenture.



2.

All corporate action required to authorise each of the English Guarantors' entry into and performance of its obligations under the Indenture has been duly taken.

        We express no opinion as to any agreement, instrument or other document other than those specified in this letter, or as to any liability to tax which may arise or be suffered as a result of or in connection with the Indenture or the Exchange Notes (when executed) or their creation and issue other than as mentioned herein. We have not been responsible for investigation or verification of statements of fact (including statements as to foreign law) or the reasonableness of any statements of opinion contained in the Registration Statement, nor have we been responsible for ensuring that the Registration contains all (and does not omit any) material facts.

        This letter is given solely for the purposes of the issue of the Exchange Notes and for the information of the persons to whom it is addressed, and may not be relied upon for any other purpose or by any other person without our written consent.

        We consent to the filing of this opinion letter as Exhibit 5.6 to the Registration Statement. We do not, by giving this consent or otherwise, concede that we are within the category of persons whose consent is required by the Securities Act or the General Rules and Regulations promulgated under the Securities Act, or that we are "experts" in relation to any matters relating to the Indenture, the Outstanding Notes, the Exchange Notes, the Exchange Offer, or the Registration Statement, other than those matters governed by the laws of England and Wales.

Yours faithfully,

/s/ White & Case

18.

The Centre of Main Interests of each of the English Guarantors is, and will remain, in England and Wales.

APPENDIX B

1.

A certificate, determination, notification, minute or opinion might be held by the English courts not to be conclusive if it could be shown to have an unreasonable or arbitrary basis or in the event of manifest error despite any provision to the contrary.

2.

Under English law, any obligation to pay additional interest in circumstances of breach or default might be held to be unenforceable on the grounds that it is a penalty and thus void.

3.

Any indemnity may be void insofar as it relates to stamp duty payable in the United Kingdom.

4.

English courts are prepared to render judgments for a monetary amount in foreign currencies but the judgment may be converted into sterling for enforcement purposes and there is no authority as to whether or not an English court would enforce a currency indemnity in the Indenture or the Exchange Notes (if any).

5.

An English court may refuse to give effect to any provision in an agreement (i) for the payment of expenses in respect of the costs of enforcement (actual or contemplated) or of unsuccessful litigation brought before an English court or where the court has itself made an order for costs or (ii) which would involve the enforcement of non-EU revenue or penal laws.

6.

Any question as to whether or not any provision of any agreement or instrument which is illegal, invalid, not binding, unenforceable or void may be severed from the other provisions thereof in order to save those other provisions would be determined by an English court in its discretion.

7.

There is some possibility that an English court would hold that a judgment on a particular agreement or instrument, whether given in an English court or elsewhere, would supersede such agreement or instrument to all intents and purposes, so that any obligation thereunder which by its terms would survive such judgment might not be held to do so.

8.

An English court may refuse to give effect to any provision of the Exchange Notes which would be inconsistent with English public policy (we are not aware of any provision of the Indenture or the Exchange Notes would be regarded as inconsistent with English public policy but it should be noted that matters of public policy may evolve over time).

9.

The courts may strike down transactions aimed at circumventing fundamental insolvency principles, for example those of mandatory set-off and pari passu distribution, pursuant to the principles of public policy relating to bankruptcy law. There is first instance case law to the effect that a contractual subordination arrangement of a debt will not fall foul of the pari passu rule if that arrangement does not seek to cause the creditor to enjoy some advantage in a bankruptcy or winding-up which is denied to other creditors. Whilst these decisions are considered by most commentators to be correct, there remains some doubt as to whether they would be followed in all circumstances. Certain provisions of the Indenture may create such an advantage and, it is sometimes said, create charges that are registrable under section 395 of the Companies Act. It is not market practice to effect registration with regard to creditors party to an Indenture.
