I agree with Mike and really question the need for AD277 and the STALLION.
Engineers are people who pull things apart to find out why they were working
so well, and they seldom work that well again [after reconstruction] and I
are one.
GFA, do we really need to do that test, has it proven anything, do we still
have the same problem, or has training procedures obviated the need. I hate
doing the test, and the huge 'bang' in my workshop, and suspect secondary
damage is greater than the risk in operation.
I for one would support the repealing/deletion of AD 277 and rely on the
Form II inspectors judgement at an annual.
Can others add their experience. Can GFA conduct a survey,.... ?

David,
You are lucky you still have a Grumman at all. It could easily have caused
the aircraft to burn to the ground.
Regarding the Tost releases:
Tost have determined that the release spring is good for at least 12000
operations. Based on 10000 operations being safe they figure on 2000
launches before overhauling the release.
For a privately owned glider which may do 50 launches a year a four year
release test interval is way overkill.
I note the "field experience" that was given as a reason in the GFA
document without any evidence or further justification. This isn't good
engineering.
