An MQ-1B Predator that crashed Jan. 17 in Southwest Asia suffered engine failure stemming from a crack in the crankshaft, according to a summary of an Air Combat Command Accident Investigation Board report. The aircraft was destroyed upon impact. The crankshaft crack caused a connecting rod to fail, wedging itself in the opposing cylinder. A recent report indicates, though, that an increasing number of unmanned aerial vehicle crashes can be attributed to operator error.
The 13th Fighter Squadron from Misawa Air Base, Japan, deployed its new F-35A fighters to a major exercise for the first time, sending them to Pacific Air Forces’ premier air combat training event: Red Flag-Alaska.
