Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
It has been found that in case of fuel leakage inside the conduit used to route the clear ice detector wiring through the wing fuel tank, it is possible to have fuel accumulation inside the conduit due to application of wiring protection sealant in the conduit end. The absence of fuel leakage detectability into the clear ice detector wiring conduit, associated with an ignition source, could result in fire or explosion inside the tank.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
