To preclude the possibility of Airworthiness Directives applicable to Piper Model PA-31 aircraft not being incorporated in aircraft which have affixed to them, in error, a model PA-31- 310 Aircraft Data Plate, accomplish the following within the next 30 days from the effective date of this AD unless previously accomplished.
(a) Ascertain whether the Aircraft Data Plate located on the lower fuselage just below the forward hinge on the main cabin door is marked with a model designation of PA-31 or PA-31-310. If it is PA-31-310, remove and replace with a correct PA-31 Aircraft Data Plate and verify that Airworthiness Directives, Piper 74-26-04, 75-09-10, 75-26-18, and 76-04-11, applicable to model PA-31 aircraft, have been accomplished. If not, comply in accordance with the requirements of those Airworthiness Directives.
(b) Upon request with substantiating data, submitted through an FAA Maintenance Inspector, the compliance time for this AD, including 74-26-04, 75-09-10, 75-26-18 and 76-04- 11 may be adjusted by the Chief, Engineering and Manufacturing Branch, FAA, Eastern Region.
