Balancing weighty matters
Every mechanic can tell you stories about aircraft idiosyncrasies. Stories abound about aircraft towing and jacking incidents. I have one about how I severely injured my back lifting the wing of a C-177 RG to change a tire because we did not have a jack available and the aircraft was blocking the taxiway.
The T-50 Bobcat was no exception. With its light, wood empennage structure and weighty motors well forward of the CG, the Bobcat would stand on its nose if brakes or other controls were misapplied at the wrong moment. This was also true when jacking, as the T-50 in level flight attitude was very susceptible to nose over. This was not a pretty sight with the aircraft five feet in the air on jacks. The answer is weight on the tail and the manual specifies this when jacking.
However, the manual depicts a neat, 75 pound, trapezoidal weight hung from the tail wheel or forward on the empennage. But how many shops have such weights handy? And hanging heavy stuff from fabric covered surfaces can present some problems.
Enter the real world. The common weight used for this purpose is sandbags. In this case, a couple of 35 pound sandbags served the purpose nicely.
As an aircraft mechanic, I get no respect. Yeah. Just the other day my wife said to me, “I thought you told me you worked at the A&P supermarket.” I tell ya, as a mechanic, I get no respect, yeah.
You wanted fifty aircrews!? I thought you said fifty airscrews! http://www.cessnat50.org/media/manuals_and_newsletters/erection_and_maintenance/erection_and_maintenance_183.pdf
