Accident Summary:
At 1200 hours 5 Jul 68, I was notified by my operations officer that an aircraft accident had occurred
at the Black Horse base camp and that I was appointed as investigating officer. I went to the battalion
safety office and learned the accident involved two (2) aircraft from the 135th Assault Helicopter Company.
I called operations, was assigned an aircraft and arrived on the scene at 1415 hours. The area was marked
off with tape and none of the debris or the aircraft had been moved. My investigation revealed that
approximately 1115 hours a light fire team composed of aircraft 66-15124 and 66-15127 had taken off from
black horse at 0650 hours that morning on a mission and had returned to their own ramp for refueling and
rearming prior to going back on station. Aircraft 66-15124 was piloted by WO1 J. L. Drolshagen and the the
aircraft commander was Australian LT Anthony A. Casadio. The aircraft 66-15127 was piloted by WO1 Jessa J.
Porter and the the aircraft commander was CWO Richard T. Harrison. Upon my arrival at the scene, they were
positioned as indicated in diagram (tab f). My investigation revealed the following facts; the fire team
leader, LT Casadio, had called the tower, landed and hovered to a point in the lanes between the revetments
and both aircraft at flight idle while the armament systems were rearmed. After rearming the fire team leader,
LT Casadio called the tower and requested clearance for the team to hover at its revetments to refuel.
Investigations showed this is company SOP to refuel in the revetments. I talked with the tower operator on
duty at the time and he stated he cleared them to hover and then turned his attention to other traffic and
did not witness subsequent events. A check with combat weather team #1, detector 32, weather squadron at
Blackhorse established the weather as 6/8 cw, 1200 ft, 8/8 cirus 30,000 ft. Temp 28 degrees centigrade dewpoint
24 degrees C visibility + 6 and winds variable at 3 knots favoring the south. The investigation revealed that
aircraft 66-15124 at approximately 1138 hours brought to a hover by LT Casadio while the gunner, on the right
side of the aircraft was still putting his helmet on and therefore not in a position to advise the pilot.
The crew chief of the left side did have his helmet on and cleared the aircraft commander to the left. As
the aircraft was lifted to a hover, it drifted right and to the rear. The aircraft commander, who was piloting
the aircraft stated his intentions were to hover the aircraft, turn the tail left and hover to his revetment.
He states and it was verified that an aircraft was parked on a pad in front of the revetments at the time and he
was concentrating on staying clear of it. As the aircraft was turned to the right, it drifted rearward and at a
point about 45 degrees angle from 66-15124, the tail rotor of the hovering aircraft struck the main rotor of the
aircraft at flight idle. Upon contact, the tail rotor, 90 degrees gear box and FM antenna separated from the
aircraft landing as indicated in diagram. The hovering aircraft then lurched tail left, became uncontrollable
and the pilot lowered the pitch. The aircraft initially made contact with the ground on the right skid, bounced
to the left and landed hard on the left skid, crushing it against the aircraft belly. The aircraft came to rest
on the left rocket tube and pylong assembly and the right skid. There was no fire or injuries to the crews and
both aircraft were shut down without further incident
