The airplane, a civilian Lockheed L-100-30(P) version of the Lockheed C-130 Hercules, registration A-1325^[7] had been on a normal flight transporting military personnel and their families to Iswahyudi Air Force Base.^[8] The plane prepared to land on base but instead crashed about 5.5 kilometres (3.4 mi) northwest of the north end of the runway,^[9] bursting into flames upon impact. Flying conditions were good and the weather was clear at the time of the crash.^{[10] [6][9]} Air control communicated with the crew minutes before the accident and indicated no issues.^[11][9] 11 of the 15 survivors were treated at Dr. Soedono Hospital and 4 at the base's hospital.^[8] All deceased were identified by the evening of May 22.^[12]

The Indonesian Air Force said it was unlikely that the cause of the plane crash would be shared publicly, a practice said to be a military standard around the world.^[13] The plane had passed inspection the day before the crash.^[11] Witnesses variously claimed seeing fire inside the plane; hearing two explosions; nuts and bolts falling to the ground up to 2km away from the crash site; and a wing snapping off the aircraft.^[14][9][11] A survivor said that "it felt like the plane's engines just stopped and then the aircraft began to break apart in mid-air."^[9] Others speculate that the Hercules series is poorly designed but the Air Force is too underfunded to afford safer planes or spare parts for aircraft they do have.^{[14][9][11][15]}
