Wing Strut attach fitting A-A11 Inspection results

Re: Wing Strut attach fitting A-A11 Inspection results

Rob is correct I have offered the same and some have called me with results too! Rob , e-mail me direct with any reports on the UK later model s
F-22's the FAA understands there has been a strut problem over there. how about. the attach fittings too! I read yours, are there others?

Re: Wing Strut attach fitting A-A11 Inspection results

Forrest: The FAA might believe there is a strut problem here because of the "volume" of transatlantic airfreight on new struts. The FAA can keep their knickers on, however. With the £/$ exchange rate as it is, it's just easier & cheaper for us to get new.

There are two F22's in the UK. The one at my field (tailwheel), the struts passed OK, but the fitting has not yet been formally inspected (although it will pass just fine).

The other F22 (nosewheel)...I have no idea about.

The one UK F21 is demolished after an accident.

The one UK F19 has new Airframes struts, and I know not the results of the fitting inspection (I will ask about this one and the other B models too).

All the other UK Taylorcraft ar B or Military models.

Hope this helps.

I never thought about the volume to the UK , that may explain the comments I got from the FAA , they can get their knickers all bunched up at times. thanks for that report!

More UK results:

G-AKVO is 1946 BC12D, Ser no: 9845 , N44045, around 3000 hours total time. No record of floats or skis but believed never fitted due to USA Arkansas location. Full fitting SB carried out with strip to bare metal and checked with tv boroscope and magnifying glass by inspector. Absolutely no corrosion. cracks or pitting found. Fitting primed and repainted, and centre lug treated with ACF50, and struts re-attached.

Hello Forest,
Thank you for collecting the inspection results and forwarding them on to the FAA contact.
Inspection was done on N96175, BC12D during January strut inspection routine, SN 8475 and no abnormality was detected as per SB NO. 2007-02.
Surface areas were cleaned, inspected, primed and protected as per SB instructions by A&P/IA. Further, the 4 struts passed inspection for the AD with flying colors. This aircraft has not been on skies or on floats in the 1600 hours TT.

[NC22211]

Re: Wing Strut attach fitting A-A11 Inspection results

Taylorcraft BL-65, 1939 NC22211 Serial #1149. Landplane only, inland based, approx. 1700 hours total time. Only outside tie down known was 10 years in the 70's. In storage before and after for about 30 years. Inspected the lift strut attach fittings per the SB, with the exception of borescoping the interior. No cracks or corrosion found. Since the plane is under restoration, will fully comply with the SB (borescoping) in the near future, including logbook entry. Still, wanted share the results so far.

1946 BC12D 65 hp N43972 s/n 7631 tta 2137 hours

on skis from time to time

probably NEVER hangared, always stored outside

fitting inspected per service bulletin using borescope, no cracks, paint blisters or rust, fabric is normally cut back from fitting to allow ventilation, been that way forever, drain holes were clear

not a surprise since this aircraft has had these fittings reinforced with a complete fitting overlay of formed 4130 sheet, essentially doublng the thickness as a result of cracks found circa 1992

Andy McAnaul was informed of this and was sent the 337 and sketches for this repair back in the fall of 2007

BC12D S/N 6628 N39969, complied with bulletin 2007-002, when all four struts were replaced with Univair struts. This plane sat idle for ten years ,and was rebuilt in 1989, never on floats. Low time airframe less than 1200 hours, no apparent corrosion. The rear struts failed the eddy current inspection. I cut one apart , it looks as strong as new. I will ship the small part to you.

Re: Wing Strut attach fitting A-A11 Inspection results

Eddy current is for CRACKS!!!! EVERYBODY LISTEN UP!! Eddy current is for CRACKS!!!!

Nothing personal Walt. The rant isn't directed at you. Just frustrated with this whole mess and thinking about a cut up strut with an unconfirmed crack and no corrosion ruined needlessly. If it had been my strut and I got an eddy current indication from the old requirement I would have followed with a dye penetrant test to locate the crack and seen if a simple weld repair would fix it. Of course I would have followed the whole process with an x-ray and ultrasonic or visual for the corrosion we are all looking for. The old requirement for eddy current WON'T FIND CORROSION. For everybody else out there, DON'T USE EDDY CURRENT TO LOOK FOR CORROSION. IT WON'T WORK!

Re: Wing Strut attach fitting A-A11 Inspection results

1946 BC12D N95345 S/N 9745 Removed struts and took them to Stork Twin City Testing. St. Paul Minn. $200.00, 1 hr while I waited, no rust or cracks. He said as good as new. SB 2007-002 complied with as per instructed. Found clean and no cracks or corrosion. I have owned his aircraft for 34 years always hangerd. No floats, it may have been on skies before I got it This aircraft is my pride and joy and is very well taken care of.

Re: Wing Strut attach fitting A-A11 Inspection results

Atta boy Hank!! Forrest has been the same way over the phones the last two days. frustrated! OWNERS for cripes sake get the latest AD's & Service Bulletins and consult with Your IA , then form a plan and do it.
One old boy pulled his struts apart ( on purpose) to prove the structual integritary and then repaired them. YES if you find lower end corrosion , they can be repaired IAW the FAR's. hang in there the NPRM on the A-A11 fitting is due soon.

Re: Wing Strut attach fitting A-A11 Inspection results

Hank, thanks for your comments, I cut the strut for my own curiosity, I gave the other three struts to a deserving person who will carefully follow through, with your comments.
