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 was noticed on assembly line an elongation of bolts connecting power leads on R700 and R701 shunts. An incorrect tightening torque value is likely to be the cause of the elongation. This condition, if left uncorrected could lead to heating, electrical arcing or smokes and could result in an in-flight loss of electrical power.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
