The investigation of personnel, parachutes, and equipment malfunctions receives the highest priority and is secondary in priority only to medical aid for the injured. It supersedes all other aspects of the operation to include ground tactical play. Prompt and accurate investigations and reporting could save lives and equipment. The report provides data to determine if a system or procedural training change is necessary to prevent future occurrences. The malfunction officer (MO) is a member of the drop zone support team. Any assistance required by the MO must pass through the DZSO or DZSTL, who controls the DZ. The MO discusses as much data as allowable with the DZSO or DZSTL prior to transmitting it to the control group. The MO and the DZSO or DZSTL normally discuss this feeder information immediately after the jump is complete.Note. AR 59-4 governs the duties and responsibilities of the malfunction officer. The following chapter provides only the minimum requirements for performing the duties of the MO. If there is a conflict between this TC and AR 59-4, follow the guidance in AR 59-4.
