Potentially Faulty Pins on Boeing 737 Aircraft Prompts Inspection Order by FAA
Prompted by reports that improperly installed and potentially faulty parts could cause certain Boeing 737 passenger airplanes to lose control, the Federal Aviation Administration — or FAA — has ordered for 1,050 of the jets operated by domestic airline carriers in the United States to be examined.
The part in question is a fixing pin for the tail of the aircraft to be replaced with an improved pin, as outlined in the following airworthiness directive summary by the Federal Aviation Administration:
“We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by reports of an incorrect procedure used to apply the wear and corrosion protective surface coating to attach pins of the horizontal stabilizer rear spar. This AD requires inspecting to determine the part number of the attach pins of the horizontal stabilizer rear spar, and replacing certain attach pins with new, improved attach pins. We are issuing this AD to prevent premature failure of the attach pins, which could cause reduced structural integrity of the horizontal stabilizer to fuselage attachment, resulting in loss of control of the airplane.”
If the pin in question was to fail, the result could cause a pilot to possibly lose control of the aircraft.
The cost as a result of the required changes is expected to be as much as $9,627.00 per aircraft, or as much as $10,108,350.00 overall.
FlyerTalk members are unfazed by this news, citing that airworthiness directives are issued on a regular basis as a precautionary method of ensuring safety in the commercial aviation industry.
