  • Gross Weight Increase

    I have a 337 from 1981 that reads "Taylorcarft heavy type strut and wing root fittings installed- Part nos BA809L and BA809R and 5/8" O.D. fiber bushings installed to increase gross weight to 1280 lbs land and 1351 lbs seaplane." Do these part numbers mean anything to anyone? This was done on a field approval before I owned the plane and the FAA now wants to know what they can reference this modification to in order to certify my gross weight at 1351. Is there a Taylorcraft drawing that could be used as a referece? The 337 says nothing about a reference to anything.

    I THINK that those part numbers mean the later F-19 style Spar-Strut fittings, which have the little square plate welded across the steel angles.

    5/8" OD bushings are slightly smaller than the 11/16" bushings called out in the usual Harer/Gilberti STC. UNLESS that is for replacing the OUTER spar bushings... and it assumes ytou already have the 11/16" root bushings.

      As I understand it, you need the C-85 engine along with the items you referred to in the 337 to increase the gross weight to 1280. The modification as noted in the 337 without the C-85 does not increase the weight from 1200.

      To go to the F19 and 1500 max gross requires the longer motor mount including C-85, starter, generator, and possibly more mods.
