Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream G150 airplanes. This proposed AD was prompted by reports of corrosion in the solder joints of the upper and lower front relay box connectors to the printed circuit board. This proposed AD would require replacement of the existing relay boxes with modified boxes. We are proposing this AD to address the unsafe condition on these products.
