Compliance
Comply with this AD before further flight after the effective date of this AD, unless already done.
Required actions
(1) Inspect the alternator main power cable and the exhaust crossover tube for burn marks, chafing, holes, and cracks, and replace any cable and crossover tube that has a burn mark, chafing, a hole, or a crack. (2) Install an additional alternator cable clamp part number MS21919WCJ6 and ensure correct routing of the alternator main power cable by following steps 1.5. through 1.9. of the Instructions in Mooney International Corporation Service Bulletin M20-340C, dated February 14, 2020.
Unsafe condition
This AD was prompted by reports of short circuit and arcing of the alternator main power cable in the engine compartment. The FAA is issuing this AD to prevent arcing of the alternator main power cable in the engine compartment. This condition, if not addressed, could result in an inflight fire and loss of engine thrust control, which may lead to reduced control of the airplane.
Affected ADs
None.
