Accident Summary:
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
