Number SH529AL

The approval of this change in type design applies basically to Aerospatiale model SA341G helicopters only. This approval should not be extended to other helicopters of this model on which other previously approved modifications are incorporated unless it is determined by the installer that the interrelationship between this change and any of those other previously approved modifications will introduce no adverse effect upon the airworthiness of that aircraft. This determination should include consideration of significant changes in weight distribution such as an increase in the fixed disposable weight in the fuselage.

The FAA approved Rotorcraft Flight Manual Supplement, dated November 26, 1974 is a part of this STC and must be carried in the helicopter at all times when operating with the Airglas Model L2700SA341 skis installed.

The FAA approved Rotorcraft Flight Manual Supplement, dated October 10, 1974 is also a part of this STC and must be carried in those helicopters which have the Airglas model L2700SA341HS skis installed on the 41.5300 series high skid landing gear.
