List of unrecovered and unusable flight recorders

Flight data recorders (FDRs) and cockpit voice recorders (CVRs) in commercial aircraft continuously record information and can provide key evidence in determining the causes of an aircraft loss. The greatest depth from which a flight recorder has been recovered is 16,000 feet (4,900 m), for the CVR of South African Airways Flight 295. Most flight recorders are equipped with underwater locator beacons to assist searchers in recovering them from offshore crash sites, however these beacons run off a battery and eventually stop transmitting. For various reasons, a flight recorder cannot always be recovered, and many recorders that are recovered are too damaged to provide any data.

By the time the main wreckage was located, conclusive evidence of a bomb explosion had been found, and it was decided that whatever additional information the recorders held would not justify the cost and difficulty of recovering them. Neither of the recorders were ever found.
1974-12-04 138 Martinair Douglas DC-8 Maskeliya, Sri Lanka Accident FDR completely disintegrated by impact. Small fragments of the foil tape from the unit were recovered from the crash site, but all of the fragments were from the supply spool of the recorder, and thus did not contain any flight data. The aircraft did not carry a CVR.
1975-09-30 240 Malév Tupolev Tu-154 near the Lebanese shoreline Unknown Resting in between 600 and 1,000 m (2,000 and 3,300 ft) of water; neither recorder found.[12]

1976-08-15 232 SAETA Vickers Viscount 785D Chimborazo volcano, Ecuador Accident Speculation surrounding the existence of both the FDR and the CVR followed the discovery of the plane's remains in 2002, after being lost for 26 years. Civil aviation authorities claimed it didn't carry any device, but a former SAETA pilot claimed that the Viscount carried at least the FDR. A former SAETA executive also claimed that the plane was acquired with both devices. In the end, due to the crash site's high altitude, harsh weather, and inaccessible and remote location, it was declared a holy field (de facto and de jure graveyard) and no investigation was made into the causes of the crash.[14]
1976-10-13 N730JP Lloyd Aéreo Boliviano Boeing 707-131F El Trompillo Airport, Santa Cruz de la Sierra, Bolivia Accident The FDR was inoperative at the time of the accident. The CVR's cockpit area microphone was inoperative and did not record any useful information as a result.[15]
1977-09-02 3751 Transmeridian Air Cargo Canadair CL-44 2.5 Nautical Miles east of Waglan Island Accident Recovery was hampered by bad weather and poor visibility. Undersea cables in the area precluded the use of dredging equipment, making salvage operations very difficult. Only 25% of the wreckage was recovered after an extensive effort; the CVR and FDR were not found.
1977-12-18 730 SA de Transport Aérien Sud Aviation Caravelle 4 kilometers southeast of Funchal Airport, Portugal Accident Aircraft was located but largely not recovered from the sea, it was not stated in the accident report which types of flight recorders were carried, only that none were recovered.[16]

1979-01-30 967 Varig Boeing 707-323C Pacific Ocean, around 200 kilometers East Northeast from Tokyo, Japan Unknown The aircraft debris was never located and thus, neither the CVR and FDR was found and the cause of the crash was never determined.[19]
1979-05-25 191 American Airlines McDonnell Douglas DC-10-10 Des Plaines, Illinois Accident The separation of engine one caused the cockpit voice recorder to cut off and lose power one second later, causing the last 31 seconds of the crash to not be recorded.[20]
1980-03-14 007 LOT Polish Airlines Ilyushin Il-62 Warsaw, Polish People's Republic Accident Both flight recorders found, however the CVR stopped working 26 seconds before the crash.
1980-12-23 162 Saudia Lockheed L-1011 Tristar Over the Gulf of Bahrain Accident The CVR was overwritten and only contained conversations after the emergency landing. The FDR malfunctioned and recorded erroneous data.
1981-05-07 901 Austral Líneas Aéreas BAC One-Eleven Río de la Plata, near Buenos Aires, Argentina Accident Neither flight recorder was ever found.[21]
1981-05-24 HC-BHG/FAE-723 Ecuadorian Air Force flight, in behalf of the Ecuadorian Government Beechcraft Super King Air Huairapungo Hill, Loja Province, Ecuador Accident (officially) The existence, and possible whereabouts, of the CVR and/or FDR has been disputed. High-ranking Air Force officers stated to a 1992 inquiry by the Congress of Ecuador that the black box equipment wasn't acquired with the plane because it was considered "optional." The acquisition expedient did not show that either device was acquired, and Beechcraft claimed that it had no record of selling or providing either device. In spite of this, and that, at least officially, none was found at the crash site, the possibility that black boxes existed has been speculated on. The head of the 1992 parliamentary inquiry criticized the Ecuadorian armed forces for cordoning off the area and removing debris without any judicial process or security protocols.[22]
1983-01-11 2885 United Airlines Douglas DC-8F-54 Detroit Metropolitan Airport, Romulus, Michigan Accident The FDR malfunctioned during the accident.[23]
1982-09-13 995 Spantax McDonnell Douglas DC-10-30CF Málaga Airport, Málaga, Spain Accident CVR destroyed by post-crash fire.
1985-01-01 980 Eastern Air Lines Boeing 727-225 25 nmi (46 km) from La Paz at the 19,600 ft (5,970 m) level of Andean peak Mt. Illimani. Accident Due to the extreme high altitude and inaccessibility of the accident location, the FDR and CVR could not be recovered.[24] A team of three mountain climbers attempted to find the recorders in 2016, recovering part of the recorder mounting rack and a magnetic tape which they believed may have come from the CVR.[25] The NTSB determined that the tape was not from a flight recorder.[26]
1985-01-21 203 Galaxy Airlines Lockheed L-188 Electra Near Cannon International Airport, Reno, Nevada Accident The FDR was inoperative at the time of the accident.[27]

1987-11-28 295 South African Airways Boeing 747-244B Combi Indian Ocean, near Mauritius In-Flight Fire CVR located at a depth of 4,900 m (16,100 ft), but the quality of the audio was very poor and only the last 30 minutes were recorded. In that, much of the conversation was unknown and the tape stopped when the emergency began, possibly due to the fire burning the wires to the CVR. FDR not found.
1987-11-29 858 Korean Air Boeing 707-3B5C Andaman Sea Bomb Neither flight recorder was ever found.[30]
1988-07-03 655 Iran Air Airbus A300 Persian Gulf Shootdown Neither flight recorder was ever found.[31]

1994-04-06 9XR-NN Rwanda Government Dassault Falcon 50 1 Nautical Mile East of Kigali Airport, Kigali, Rwanda Shootdown The whereabouts and even the existence of the CVR and/or FDR has been disputed. Multiple independent investigations have been unable to determine the location of any flight recorders the aircraft may have carried. A proper examination of the crash site was not conducted until 15 years after the shootdown, by which time a majority of the wreckage had been displaced or scavenged.[44] The manufacturer performed maintenance on the airplane a year before the crash, during which they documented that no recorders were installed (though mounting racks were in place for the operator to install them if they later decided to).[45] Rwandan aviation laws at the time required all airplanes used for transporting the head of state to carry both a CVR and an FDR. The possibility that recorders were installed at some point between the work performed by Dassault and the shootdown has not been ruled out.
1994-12-21 702P Air Algérie, leased from Phoenix Aviation Boeing 737-200 Willenhall, Coventry Accident The FDR did not record any data from the accident flight.[46]
1995-08-09 901 Aviateca Boeing 737-200 San Vicente, El Salvador Accident The FDR was not found at the crash site, possibly scavenged from the site by locals.[47]
1995-12-20 41 Tower Air Boeing 747-136 John F. Kennedy International Airport, New York City Accident The FDR was inoperative during the accident due to a data acquisition unit problem.[48]
1996-02-29 251 Faucett Perú Boeing 737-222 Ciudad de Dios, Cerro Colorado District, near Arequipa, Peru Accident The FDR was usable, but the partly-burned and partly-damaged CVR had its magnetic tape broken at its beginning and only recorded isolated Spanish-language voices, possibly made during maintenance duties. Thus there was no recording of the flight crew's final moments before the crash. The airline claimed to have acquired the CVR in mid-1995, and to have done maintenance on it in two occasions immediately prior to the crash; however, the CVR's interior showed December 1989 as the date of its last opening.[49]
1996-06-09 517 Eastwind Airlines Boeing 737-2H5 Richmond International Airport, Richmond, Virginia Incident CVR overwritten.[50]
1996-10-22 406 Millon Air Boeing 707-323C Manta, Ecuador Accident The FDR presented malfunctions that precluded precise and full readouts of its data. The device was reportedly retrofitted into the aircraft and also lacked adequate documentation.[51][52]

2004-10-14 1602 MK Airlines Boeing 747-244(SF) Halifax Stanfield International Airport, Halifax, Nova Scotia Accident CVR was exposed to extreme heat for an extended period which melted the recording tape.[63]
2005-02-03 904 Kam Air Boeing 737-200 Pamir Mountains, Afghanistan Accident Crash site located at a near inaccessible area of the Pamir Mountains. Most of the wreckage was buried in deep snow, and specialists had to clear landmines from the area before it could be accessed. FDR found with extreme difficulty (though it did not contain data due to a pre-existing fault in the data acquisition unit). The CVR was never found, and at least one investigator was killed during the search.
