An Robertson Aircraft FAA Approved Airplane Flight Manual Supplement is required for each model. (See STC Addendum)
The approval of this change in type design applies basically to Piper PA34-200/PA34-200T models only. This approval should not be extended to other aircraft of these models whose type design differs significantly or on which other previously approved modifications are incorporated unless it is determined that the interrelationship between this change and any other type design changes or previously approved modifications will introduce no adverse effect upon 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. A copy of this Certificate and STC Addendum SA154NW shall be maintained as part of the permanent records for the modified aircraft.
