An Aer Caribe Antonov AN-32, registration OB-2120P performing a cargo flight from Lima to Iquitos (Peru) with 4 crew, was on approach to Iquitos's runway 06 at about 13:21L (18:21Z) but reported mechanical problems with the landing gear. The aircraft subsequently ended up at the side of the runway, broke up and burst into flames. The 4 crew were rescued and taken to a hospital with minor injuries. The aircraft was destroyed.
Peru's Government announced OB-2120P on a cargo flight from Lima to Iquitos suffered a mistake at Iquitos during landing.
On Nov 18th 2020 Ukraine's NBAAI reported they have appointed an accredited representative to join the investigation led by Peru's accident investigation. The aircraft approached runway 06, touched down on the runway about 1225 meters past the runway threshold, the crew turned off the "PROPS STOP Switch", which caused a gradual and uncontrolled turn to the left, the aircraft went off the paved surface of the runway about 250 meters after touchdown/1475 meters past the runway threshold, crossed a drainage ditch resulting in the destruction and separation of the right hand halfwing, the right hand engine, the right hand main gear and the outbreak of fire. The 4 crew (no passengers on board) were taken to a hospital for examination. Airport Rescue put the fire out.
Peru's CIAA released their final report in Spanish only (Editorial note: to serve the purpose of global prevention of the repeat of causes leading to an occurrence an additional timely release of all occurrence reports in the only world spanning aviation language English would be necessary, a Spanish only or no release does not achieve this purpose as set by ICAO annex 13 and just forces many aviators to waste much more time and effort each in trying to understand the circumstances leading to the occurrence. Aviators operating internationally are required to read/speak English besides their local language, investigators need to be able to read/write/speak English to communicate with their counterparts all around the globe).
The report concludes the probable causes of the accident were:
Runway Excursion due to loss of direction control of the aircraft after landing due to disconnecting the propeller stops for aerodynamic braking at a speed higher than established resulting in an uncontrollable turning moment to the left due to asymmetric thrust of the propellers.
Contributing factors:
- unstabilized approach without going around
- landing with asymmetric thrust by the propeller without going around
- probable failure of the KTA Fuel Regulator of the Automatic Engine Power and Rotation Frequency Regulation System, which prevented the reduction of power on the #2 engine to operating regimes for approach and landing
