Designing the Engine Mount for ROTAX’s 915iS, incorporating the same Lycoming 0-235 propeller spinner tip coordinates consumed many, many hours that turned into days, then months! An RFQ was sent to Aerospace Welding, Inc. (AWI) on May 13. Following clarifications, a PO was awarded on June 24, 2019.
This is N724DT’s Initial tack-welded, engine mount fabricated by Aerospace Welding, Inc. One change of tube ID on four (4) tubes on the engine side (my mistake) set the project back one month.
