Otter 270 was delivered to the United States Army on 21st June 1958 with serial 57-6128 (tail number 76128). It was allocated to the 12th Aviation Company at Fort Sill, Oklahoma and was to spend its entire Army career assigned to this unit. In August 1961 it flew north to Fort Wainright, Alaska when the Company was re-assigned to Alaska to join the Yukon Command.
76128 is mentioned honourably a few times in the unit history of the 12th Aviation Company. On 31st March 1971 it made history when a native child was born aboard the Otter while it was en route to Bethel. Temperature outside the aircraft at the time was 40 degrees below zero. On 8th September '71, flown by Captain William Brown, 76128 landed at McGrath en route from Bethel. After refuelling, he was informed of a native high school student who had badly injured his hand in an accident. Captain Brown immediately loaded the student aboard the Otter and flew on to Fort Wainwright, where medical facilities were better equipped to handle the emergency. Mid October '72 found 76128 flying to several native villages in the bush. The Bureau of Indian Affairs needed to contact the natives of the Yukon River Drainage Area, and due to its excellent short field performance, the Otter was dispatched and spent two days flying in support of this government agency.
76128 was one of three Otters still flying with the 12th Aviation Company when it was inactivated on 21st June 1973, and was present at the stand-down ceremony held that day at Fort Wainright. In August 1973 the Otter is recorded as being donated to a vocational school, but ended up with the Alaska Wing of the Civil Air Patrol (CAP), in storage at Ten Mile Pond outside Anchorage. It had 4,750 hours on the airframe at that stage. Also in storage at this location was Otter 329, tail number 81712, which had also been transferred to the CAP by the US Army. The Alaska Wing of the CAP was somewhat under-funded at the time, and greatly welcomed receipt of such aircraft as the Otters from the Army, which could then be sold on. In July 1975 Mr William J .Bennett of Gander Aviation Ltd, Gander, Newfoundland bought these two Otters from the CAP. When he arrived at Ten Mile Pond, he found 270 to be in a dilapidated state but with a good engine. 329 was in a good state but its engine was shot. He swapped engines, putting the good engine on 329. Canadian registrations were allocated for both aircraft, number 270 becoming C-GLFK and 329 becoming C-GLFL. Number 329 was then flown back to Gander, but due to its poor condition, number 270 was taken by ship from Anchorage to Vancouver and then overland across the country to Gander for rebuild.
Number 270 C-GLFK performed its first test flight after the rebuild at Gander on 9th February 1977 and entered service with Gander Aviation Ltd. It was to fly for this company for the next thirteen years, serving both the island of Newfoundland and mainland Labrador. Only one incident is recorded, on 3rd March 1987 when the Otter made a precautionary landing after engine failure at Kelly's Pond, Newfoundland. It was repaired and returned to service. On 13th March 1990 it was registered to North Air Ltd., Gander, an associated company of Gander Aviation Ltd. It was leased to Trans Cote Inc for the summer of 1991, based at Aéroport du Blanc Sablon, Québec on the north shore of the St. Lawrence. It then returned to Gander and last flew for Gander Aviation Ltd., in November 1991. It was then sold to Ketchikan Air Service Inc., who collected the Otter at Gander and flew it all the way to Ketchikan, the aircraft returning to Alaska from where it had come. It was registered to its new owners as N51KA on 4th May 1992. It was converted to a Vazar turbine Otter, arriving at Vancouver on 2nd February 1993 for the conversion, which was carried out by Aeroflite Industries. It then flew back to Ketchikan and flew as part of the Ketchikan Air Services fleet for some years.
The Otter was sold to Pantechnicon Aviation Inc., a leasing company, of Glenbrook, Nevada to whom it was registered N270PA in January 1997. Following the closing down of Ketchikan Air Service in March 1997, another Ketchikan-based air carrier, Pro Mech Air, arranged to take N270PA as well as two other turbine Otters on lease from Pantechnicon Aviation. The Otter returned to Ketchikan, resplendent in Pro Mech's colour scheme, and was registered to Pro Mech Air in April 1998 and commenced flying their scheduled services out of Ketchikan. It was still flying for Pro Mech Air in 2004.
