Potentially Faulty Pins on Boeing 737 Aircraft Prompts Inspection Order by FAA

Could this tail of a Boeing 737-800 aircraft operated by Alaska Airlines be one of the tails with a substandard attach pin?


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.

    Unfazed? Airworthiness directives are issued on a regular basis? I’m sure none of those directives are always on the scale of “if it fails the pilot would have no control of the aircraft”, or speak in plain languages: “Say goodbye to Kansas, you’re going down!” This isn’t a precautionary method, this is a seriously safety issue. I’m sure people will cite evidence that 737 is the most popular plane and has no crashes related to this particular issue yet, but of course we always regret it when tragedy happens and asks: “why isn’t anything done with this sooner!”, when that happens, just remember your “unfazed” comment.

    I am dating myself, but years ago the 737 had another flight control issue, and memory serves me correct it caused at least one bird to go down near Pittsburg. After they fixed that it’s been fine ever since.
    Now I am wondering how this ” pin” issue came about?
    Wonder why AS “hawaiian” bird was depicted ?

    Of course I am reading this at 39,000 feet on a 737 ORD-SJU. Maybe I should stop logging into Flyertalk while I am on GoGo.

    what about us about to get on a 37 overseas? will this be followed in the EU?
