Safety record

Accident & incident history

1996-04-03 Incident · Traverse City, MI Damage: Minor NTSB · CHI96IA125
Reported aircraft: ATR 42 — a different aircraft that carried the N421MQ registration before this airframe.
Probable cause: improper use of procedures by maintenance personnel at an overhaul facility during overhaul of the landing gear, allowing corrosion to occur on the barrel lugs of the landing gear, which subsequently led to fatigue cracking of the lugs and eventual collapse of the gear.
1988-01-19 Incident · Waterloo, IA Damage: Minor NTSB · CHI88IA045
Reported aircraft: Aerospatiale ATR-42 — a different aircraft that carried the N421MQ registration before this airframe.
