Hello Tim
I looked at a Trigear with a 912S that has a Airmaster prop, and the spinner was
cracked for a second time in a hundred hours. he had it welded the first time,
and i saw that all the screws was not seated all the way.
I had a Airmaster on order at the time and asked Martin bout cracking??? He said
the newer spinners have a new location of mounting holes that help a lot to
not crack. he probably said they do not crack anymore. i also had concern as the
front mount was not real tight, he said to wrap electrical tape to get a nice
tight fit.
Also it is probably not a good idea to push plane from spinner.
Good Luck.
Sincerely
Ron Parigoris

replaced the metal spinner according the techlog due to a crack at 288 flying
hours. Now, 2 years later at 480 flying hours there develloped again a crack
in that "new" spinner.

piece to the spinner. But I would like to know if the suggested cure of Gehling
is allowed and will hold.
