Lockheed L-1329 JetStar

On approach to Guadalajara-Miguel Hidalgo y Costilla Airport, the crew contacted ATC and reported that all hydraulic systems failed. After being able to lower the undercarriage manually, the crew continued the approach but landed on runway 10 in a flapless configuration. Because the brakes and the thrust reversers were unserviceable, the crew was unable to stop the aircraft within the remaining distance. The aircraft overran, struck a drainage ditch and came to rest 300 metres past the runway end. All occupants were rescued, among them five were slightly injured.

The aircraft was completing a flight from Kish Island to Tehran with an intermediate stop in Isfahan. Shortly after takeoff from Isfahan-Shahid Beheshti Airport, while climbing to the altitude of 2,000 feet, the crew reported pressurisation problems and was cleared to return for an emergency landing. Five minutes after its departure, the aircraft went out of control and crashed few km from the airport. All 12 occupants were killed, among them General Mansour Sattari, Chief of the Iranian Air Force.

Completing a flight from Istanbul to Southampton, the aircraft flew a procedural ILS and landed on runway 20. The crew report that they encountered wind shear on the final approach and they increased power to compensate for a loss of 10 knot of airspeed. The aircraft landed some 500 feet into the runway and, after touchdown, maximum braking appeared to be ineffective. The crew suspected aquaplaning and activated reversed thrust but they report that correct deployment was not indicated on the flight deck and so they assumed that it was not operating. Despite weaving along the remaining 1,500 feet of runway they were unable to prevent the aircraft from over running the end. The aircraft came to rest some 75 metres into the grass area beyond. Debris, consisting of earth and stones was ingested by the engines and the right wing tank was punctured. An inspection of the runway 10 minutes previously showed that, although the runway was wet, there was no standing water. A runway friction test was carried out at 1646 hrs and this gave the friction on the first, second and third runway segments as 0.67 Mu, 0.66 Mu and 0.57 Mu respectively.

Flight was a 3-engine ferry with the #4 engine shut down. During takeoff roll at V1 the #2 engine overheat light came on. According to the copilot the pilot reduced throttle slightly and continued the takeoff. After lift-off the pilot aborted the takeoff. The airplane could not be stopped on the remaining runway and collided with antennas, approach lights and a construction site 1,180 feet from the departure end of the runway. Postcrash exam of the 3 operating engines did not reveal any evidence of mechanical failure or malfunction. A failed resistor was found in the #2 engine electronic engine control (eec). This would cause the unit to over-schedule fuel to the engine resulting in hotter engine operating temperatures. Retarding the throttle would reduce fuel flow to within normal ranges for engine operation. Under conditions that existed at the time of the accident, the airplane would have a 3-engine rate-of-climb of 1,398 fpm, and a 2-engome rate-of-climb of 350 fpm. The captain was killed while the copilot was seriously injured.

The crew was completing a positioning flight from Mitiga to Algiers. After takeoff from Mitiga Airport, while climbing to an altitude of 7,000 feet, the airplane disappeared from radar screens and the contact with ATC was interrupted. SAR operations were initiated but eventually abandoned after eight days as no trace of the aircraft nor the crew was found. It is believed that the aircraft crashed in the Mediterranean Sea and lost without trace.
