| Disposition of the CH-47C Helicopters |
| In service to the United States Army |
| As of December 2002, we had generally a good idea what became of most of the 270 C model Chinooks manufactured for the U.S. Army. Many of the details surrounding the demise of most of the known lost aircraft has remained a mystery. There are no known surviving C models. |

| Airframe Losses |
| [Excluding those lost in the Republic of Vietnam] |
| --- Crashed in the Federal Republic of Germany (FRG) --- |
| On 13 June 1975, one airframe was lost due to mechanical failure when it suffered a number 2 engine failure, and due to high gross weight, could not maintain flight: |
|
| On 11 September 1982, one airframe was lost due to mechanical failure of the forward transmission, resulting in the worst helicopter accident in history: |
|
| On 15 July 1977, one airframe was lost due to a mechanical failure on the ground during a maintenance operational check (MOC) when the rotor system de-phased: |
|
| On 25 February 1980, one airframe was lost due to a mechanical failure during a maintenance test flight when, during the Turbine Engine Analysis Check (TEAC), the combining transmission phasing mechanism decoupled allowing the rotor system to mesh: |
|
| --- Crashed in Columbia, South America --- |
| On 20 November 1987, one airframe was lost due to an accident in Columbia when the engines flamed out after ingesting un-purged water from the internal extended range fuel tanks: |
|
| --- Crashed in Panama, Central America --- |
| On 15 June 1987, one airframe was lost due to an accident in Panama when, during a Night Vision Goggle (NVG) training mission, the aircraft bounced off the water severely damaging the structure. The aircraft was subsequently landed in the shark barricaded swimming area at Fort Sherman where the salt water consumed the airframe: |
|
| --- Crashed in Peru, South America --- |
| On or about 1 May 1970, one airframe was lost, details unknown: |

|
| --- Crashed in Hawaii --- |
| On 5 August 1976, one airframe was lost due to mechanical failure. While taxiing for takeoff, the aircraft violently shuddered and disintegrated. An old style shim was installed in the aft transmission during overhaul that caused it to fail: |
|

| On 17 July 1980, one airframe was lost due to accident when the aircrew attempted to cross mountainous terrain near Twenty Nine Palms with insufficient power available: |
|
| --- Crashed in Michigan --- |
| On 11 July 1983, one airframe was lost due to accident when, flying at night under night vision goggle devices (NVG's), the aircraft stuck a small island and crashed: |
|
| --- Crashed in Arkansas --- |
| On 15 May 1987, one airframe was lost due to mechanical failure when the number 2 generator went off-line. When the pilot attempted to reset it, the generator caught fire: |
|
| --- Crashed in Alaska --- |
| On 12 July 1979, one airframe was lost due to an accident when, after landing, a parashoot was pulled into the aft rotor system causing the rotor systems to dephase: |
|
| --- Crashed in Virginia --- |
| On 20 March 1983, one airframe was lost due to mechanical failure off the coast of Cape Henry, when the forward swiveling actuator to transmission attaching bolt failed: |
|
| --- Crashed in New Jersey --- |
| On or about 12 January 1972, one airframe was lost in an accident during a Boeing company test flight (details unknown): |
|
| --- Crashed in The Republic of Korea (South Korea) --- |
| On 2 March 1977, one airframe was lost due to an accident when the aircraft encountered weather below visual flight rule (VFR) minimums and continued the flight in mountainous terrain until striking a set of six high tension power cables: |
|
| On 16 February 1984, one airframe was lost due to mechanical failure when the number one engine transmission failed: |
|

|
| One airframe was lost in a mid air collision with a United States Air Force (USAF) O-2: |
|
| One airframe was lost, when following an accident and having landed, was deliberately destroyed by air strike to prevent capture by the enemy: |
|
| One airframe was lost, when damaged on the ground beyond repair, details unknown: |
|
| One airframe was lost while on a mission to Cambodia, details unknown: |
