## The airworthiness directive

62-11-04 HUGHES: Amdt. 438 Part 507 Federal Register May 15, 1962. Applies to Model 269A Helicopters Equipped With Lycoming Model 0-360-C2D Engines of Serial Numbers L-3816-36 Through L-4599-36 and L-4601-36 Through L-4640-36.

Compliance required within 50 hours' time in service after the effective date of this directive.

Because of revisions to the operating limitations necessitated by changes in engine camshafts which resulted in a reduction in maximum horsepower, the FAA approved Flight Manual shall be revised to incorporate the new operating limitations as set forth in Hughes Model 269A Flight Manual revised page 24A.

When engines modified to incorporate a new camshaft in accordance with Lycoming Service Instructions are installed, the aircraft may be operated in accordance with original operating limitations.

This directive effective May 15, 1962.
