Up-to-date with what we know as of 14 June 2009, this listing shows the original tail number, the conversion tail number, the type aircraft each Chinook was converted to, and the status of the airframe. The last column, labeled "Age", shows the airframe age based on the day the U.S. Government accepted the helicopter (the DD Form 250 Date). The airframe is slightly older than this figure due to the fact that each helicopter is test flown to ensure that it meets specifications prior to delivery. However, this figure is generally small (a month, in most cases, or two). |
