Makes named: textron aviation, raytheon, hawker beechcraft. Models named: 76. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
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.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
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.
Unsafe condition
This AD was prompted by cracks found in MLG “A” frame assemblies. The FAA is issuing this AD to detect and correct cracks in the MLG assemblies, which, if not addressed, could result in failure of the MLG assemblies and lead to loss of control of the airplane during landing.
Affected ADs
This AD replaces AD 97-06-10, Amendment 39-9967 (62 FR 12949, March 19, 1997) (AD 97-06-10).
