History of the Flight
On 20 October 2015, a Tecnam P2006T aircraft, registration PK-LTK, operated by PT. Asian One Air, was conducting an unscheduled solo flight training. The purpose was to gain flight hours for a newly recruited pilot. The flight was planned from Husein Sastranegara Airport (WICC) in Bandung, West Java, to Nusawiru Airport (WICN) in Pangandaran, West Java, and return to Bandung.
The aircraft departed Husein Sastranegara Airport at 0950 LT (0250 UTC), cruised at 7,500 feet, and was scheduled to arrive at Nusawiru Airport at 0310 UTC. The pilot was the sole occupant. No technical abnormalities were reported before departure or during the flight up to the time of the incident. The flight from Bandung until descent was uneventful.
At 0257 UTC, the pilot reported to the Nusawiru Aerodrome Flight Information Services (AFIS) officer the position over TASIK (Tasikmalaya) at 7,500 feet. The weather during approach was suitable for Visual Flight Rules (VFR), with easterly winds at 7 knots.
There were eight other aircraft in the vicinity: five conducting area training, one performing touch-and-go training, one departing, and one arriving. Two additional aircraft were on the ground ready for taxi.
Approximately 15 nautical miles before Nusawiru Airport, the aircraft descended to 2,000 feet then proceeded directly to the final approach for runway 07. The pilot stated that during final, the landing configuration was set and the checklist was read.
At 0316 UTC, the aircraft landed on runway 07. After touchdown, the pilot informed AFIS personnel that the landing gear was not extended. The pilot did not recall activation of any warning. The pilot shut down the engines and evacuated the aircraft. The aircraft came to a stop about 400 meters from the touchdown point. Airport Rescue and Fire Fighting (ARFF) personnel responded. No injuries occurred. The aircraft sustained damage to the lower fuselage skin and the VOR/DME antenna.

The pilot was the only person on board. No further personnel details were provided in the report.

Analysis
(Note: Analysis from the source is included here as factual information from the report.) The investigation concluded that the flap full down position with the landing gear UP did not trigger the landing gear warning, which may have prevented the pilot from being aware that the landing gear had not been extended. Additionally, stress and fatigue might have degraded human performance, combined with inappropriate checklist execution, resulting in the landing gear not being extended.
