Brief Description: Replaced AN4-50A Bolts With AN4-47A Bolts
I replaced all four of the incorrect length AN4-50A bolts in the engine mount pins with AN4-47A bolts and AN363-428 nuts. Tightened all four bolts/nuts to the Jabiru specified 8 ft/lbs (96 in/lbs) of torque.
Properly sized AN4-47A engine mount bolt with proper AN363--428 nut.
Top-right engine mount with proper bolt and nut torqued to 8 ft/lbs with correct comression distance.
Top-left engine mount with proper torque and compression distance.
