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:
During a scheduled maintenance inspection on the MLG [main landing gear], the bogie stop pad was found deformed and cracked. Upon removal of the bogie stop pad for replacement, the bogie beam was also found cracked. * * * * * A second bogie beam crack has subsequently been found on another aircraft, located under a bogie stop pad which only had superficial paint damage.
This condition, if not detected and corrected, could result in the aircraft departing the runway or to the bogie detaching from the aircraft or gear collapses, which would all constitute unsafe conditions at speeds above 30 knots. * * * * *
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
