Procedure
New B787 aircraft arrived for post-delivery mod. The NLG drag brace pivot link hollow bolt will accept the gear pin snuggly from LH side while the correct locking hole is 3 inches away and 'unmarked.' An inexperienced mechanic could accidentally place the locking pin in the wrong hole leading to gear collapse during ground testing damaging the aircraft and potentially injuring or killing persons in the vicinity of the gear.Apply sealant or similar mitigation to the LH inside bolt hole; mark correct hole with red outline. Has previous Engineering Authorization been implemented on the fleet?
B787 Maintenance Technician reported the nose gear pin can mistakenly be installed into the NLG drag brace hollow bolt rendering the gear unsafe for ground testing.
