Of greatest concern to Shi is that many NHJ parts are “safety sensitive,” and one is “safety critical.”

One part (Part number: P665A0039–02) is the blocking or mounting lug of the Boeing 737’s spoiler. This is a “Single Point Of Failure (SPOF)” part; if this part fails, the entire system will fail, which may cause a fatal accident.

According to a purchase list provided by Shi, Moog has bought 6986 SPOF parts from NHJ during 2015-2017. Shi said these parts can be used to equip more than 600 aircraft, as each 737 uses 10 pieces.

Shi said Moog is the exclusive supplier for all models of the Boeing 737, including the Max planes, and NHJ is the only supplier for this SPOF part for the 737 spoiler. His conservative estimate is that 500 Boeing planes may have been compromised, and are still in service.
