• Minded: DC-9-15F Description of Type Design Change:

Installation of Hughes Airwest Galley Assembly, P/N RW 2530051, in accordance with FAA sealed Hughes Airwest Drawing List No. RW 2530056.

Similar dfundium. The approval of this change in type design applies basically to the DC-9-15F airplane only. This approval should not be extended to other aircraft 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 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 tuse age.
