P W1 MARSHALL TH
IP O4 GORDON JJ
MAJ Gordon was preparing WO Marshall to assume the duties of unit instructor pilot in the UH-1C, and had been flying with him for approximately two weeks. At approximately 1440 hours 1 Oct 68, MAJ Gordon and WO Marshall departed Flanders Army heliport and flew closed traffic to the Dong Ba Thin airstrip which is approximately 500 meters northeast of Flanders. Major Gordon was in the right seat of the aircraft as is customary when training instructor pilots, and he made the first approach to the north sod area at Dong Ba Thin. This area is normally used in training and checkouts by all rotary wing units in the Nha Trang - Cam Rhan area. Reasons for using this area include: Control tower operating on both UHF and FM, good fire fighting facilities, limited fixed wing traffic, several smooth sandy areas for autorotations and generally stable winds. After landing on the north sod, MAJ Gordon turned the controls over to WO1 Marshall who made three normal approaches to the same area. Major Gordon took the controls and demonstrated a hovering autorotation, then WO Marshall completed two in a very satisfactory manner. MAJ Gordon was cleared to move to the south sod for more hover work, notably hovering autorotations while moving forward. He demonstrated the first maneuver, then WO1 Marshall completed the next one. WO1 Marshall brought the RPM back up to 6600, then slowly and smoothly applied collective pitch. The left skid came off the ground first, the exact distance is unknown but estimated to be approximately five to six inches, and the aircraft began to roll to the right. WO1 Marshall decreased the collective pitch and Major Gordon got on the controls with him, making sure that the pitch was bottomed, but the aircraft continued to roll to the right. Cyclic was in the lateral neutral position, possibly a little left of center. The aircraft continued rolling right. Both Major Gordon and WO1 Marshall experienced hearing or feeling several "jolts" or "thumps" prior to the main rotor blade striking the ground. The chronological sequence of events is not clear due to their rapidity of occurrence, but it is known that the main rotor struck the ground, the main rotor mast sheared, the transmission was torn loose and thrown from the aircraft, various parts of the tail rotor, synchronized elevator, and tail pylon were torn from the aircraft, and it continued rolling to the right, coming to rest inverted
