one time flight

[mrjpc130h]

does anyone knows about 1 time ferry flight procedure for suspected minor crack on the wing or fuselage it self

[Dan Wilson]

If its a minor crack I don't see where the 1 time flight comes in, usually you get into that category with a major crack or a crack in a critical location and neither would be classified as minor.

In the fuselage itself I cant see any crack as being major or critical, you may end up with a no pressure flight restriction but that's about it. The critical part in the fuselage would be in the chine angles, sloping longerons or something along those lines, and once again either it would be a K writeup or it would be a major problem.

Now I have done OTF's for sever wing cracks, that was on 62-1857 (or maybe it was 1818?) and it sat on the ramp at Keesler for 6 months or so until they finally made up their minds to OTF it to Hayes for repair. Restrictions on the flight were (If I remember right)

1) Min Fuel (and it specified how much fuel in what tanks and how much in had to remain in each tank for landing).

2) Min Crew

3) VFR only

4) No forecast turbulence

5) Less than 150 FPM sink rate on landing

There may have been other restrictions as well but its been many many years (1988).

Normally these restrictions are unique and do not have set rules.

The restrictions are determined by consultation between the Ops folks, MX folks and WRALC and possibly Lockheed Tech Reps, and the restrictions will be tailor built to the specific flaw on the aircraft and degree of severity/danger factor of that flaw.

The 7ACCS ops officer added on his own restriction, the min crew selected was all persons that had PCS orders in hand and replacements had already shown up on base, that way if the bird went down he wasn't out any flight crew:eek:

If you had a specific malfunction/flaw you were referring to, let us know and you could get a better answer but a nebulous "what if" can only get a nebulous answer.

i wish tht,there is a refernce regarding OTF matters...books or any guidance to do so... but at least i got an idea of wht u talking about...thx

If its a specific problem with one of your aircraft, your folks need to give Lockheed a call (or a local tech rep for Lockheed).

In the USAF we call WRALB (Warner Robbins Air Logistics, they are the C-130 program managers for the US birds), they will need to tell Lockheed what is wrong, and between y'all and them, they will work up specific restrictions for a one time flight to a repair facility (which repair facility depends on what is closest to you that has the capability to repair whatever is ailing the plane).

A technical assistance request (TAR) should have been submitted to WR-ALC. The specific flight restrictions will be provided in the TAR. That is if the crack exceeds T.O. limitations. If the crack is within T.O. limits then the flight restriction, if any, will be provided there.

Not sure about a OTF with a crack. We were in Columbia with the flaps stuck at 50% and could not repair the problem. Got a OTF waiver to fly to PR after getting the Wing to signoff then a MAJCOM signoff. Of course we had to fly back with several restrictions like Dan mentioned above.
