Airworthiness Directive · Amendment 39-21500 · Landing gear
Textron Aviation Inc. Airplanes
This AD applies to Textron Aviation Inc. (type certificate previously held by Raytheon Aircraft Company, Hawker Beechcraft Corporation, and Beechcraft Corporation) Model 76 airplanes, serial numbers ME-1 through ME-437, certificated in any category, except airplanes with main landing gear (MLG) “A” frame assemblies part number (P/N) 105-810023-0083 (left) and P/N 105-810023-0084 (right) installed.
The FAA is superseding Airworthiness Directive (AD) 97-06-10 for certain Raytheon Aircraft Company (type certificate now held by Textron Aviation Inc. (Textron)) Model 76 airplanes. AD 97-06-10 required repetitively inspecting the main landing gear (MLG) "A" frame assemblies for cracks and replacing any cracked assembly. Since the FAA issued AD 97-06-10, the replacement parts have also experienced failure due to cracking. This AD requires magnetic particle inspections of the MLG "A" frame assemblies for cracks and replacement of the affected parts if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Within 100 hours time-in-service (TIS) after the last dye penetrant inspection required by AD 97-06-10 or within 12 months after the effective date of this AD, whichever comes first, and thereafter at intervals to not exceed 100 hours TIS or 12 months, whichever occurs first, do a magnetic particle inspection for cracks on the left MLG “A” frame assembly P/N 105-810023-3, 105-810023-67, or 105-810023-75 and the right MLG “A” frame assembly P/N 105-810023-4, 105-810023-68, or 105-810023-76 and, before further flight, take all necessary corrective actions. Do all actions by following the Accomplishment Instructions, paragraphs 4 through 13, of Beechcraft Mandatory Service Bulletin SB 32-4156, dated May 3, 2019.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
