- The Department of the Army identifies CH-47D aircraft as affected by conversion of T55-L-712 engines to T55-GA-714A configuration; the Army's CH-47 procurement context describes the heavy-lift helicopter as powered by two T55 turbine engines. Placement and stage are left unspecified because the cited evidence does not state them.
