At 0905 hours on
14 Mar 1967, Major Dubberly as Instructor Pilot, First Lieutenant
Jach as Co-pilot and Staff Sergeant Wolpert as Flight Engineer in a
C-7A took off from Holloway Air Field, RVN, with seventeen
passengers.
As the aircraft was climbing through 4500 feet,
approximately 1500 feet above the ground, a slight smoke odor was
noticed by the crew members. All instrument and circuit breakers
were monitored with no abnormal indication noted. The side cockpit
windows were closed and the smell diminished. The climb was
continued with level off and cruise power established at 7500 feet.
Approximately ten minutes later an acrid smoke odor was again
detected. All instruments and engines were scanned and Major Dubberly left his Co-pilot's seat, he was acting as Instructor
Pilot, and tried to assist the flight engineer, SSgt Wolpert, in
locating the source of the smoke. Smoke in the cabin was now
affecting the passengers eyes, an all effort to locate the source
was ineffective. Because the intensity of eye irritation was
increasing, SSgt Wolpert opened the aft cargo door to help alleviate
the smoke. First Lieutenant Philip E. Jach, flying from the left
seat, had started a descent toward Phu Cat Air Base, RVN, as Major
Dubberly was strapping himself into the right seat.
While
descending through 5,000 feet and approximately 10 miles from Phu
Cat Air Base, the number one engine fire light for zone two and
three illuminated. Engine inflight fire procedures were
accomplished but the propeller would not feather. Both fire
extinguisher bottles momentarily diminished the now blazing fire.
Fire was seen to be burning well aft of the firewall and back toward
the left wing. Maximum power was applied to number two engine and a
three to four hundred foot per minute descent was the best
performance attainable.
Major Dubberly advised the Phu Cat tower of
his emergency, had the passengers briefed and continued his descent
for a straight-in approach to Phu Cat Air Base. At 1,000 feet,
attempts to lower the landing gear proved unsuccessful, the gear
controls had been burned away by this time. Still with maximum
power on number two engine, number one propeller windmilling and
zero flaps, Major Dubberly and Lt Jach continued the approach.
By
now number one engine had burned many pieces off the nacelle and
flames were engulfing part of the wing. Bringing all his flying
experience to bear, Major Dubberly took control of the aircraft from
Lt Jach, crossed the end of the runway and touched the aircraft down
on the fuselage. The aircraft slid 657 feet and came to a rest on
the center line of runway 01. All aircraft power was turned off and
the 17 passengers and crew of three evacuated the still burning
aircraft. The base fire fighters quickly extinguished the fire.
Subsequent investigation cited enemy action as the cause of the
fire. Because of both Major Dubberly's and Lt Jach's crew
coordination, pilots skill and professionalism during a critical
emergency, and SSgt Wolpert's outstanding ability in rebriefing and
controlling the passengers, all aboard escaped without injury. For
their part in this harrowing emergency, all aircrew members were
nominated for the Air Force Well Done Award.
