History of c/n 152 from Karl E. Hayes' monograph on the deHavilland Otter (text abbreviated by Webmaster):

Otter 152 was delivered to the United States Army on 10Oct1956 with serial 55-3296 (tail number 53296).
Although most of the U-1As being delivered at this time were painted olive drab, 53296 was painted in the 'Army Arctic' scheme of white overall with high-visibility red on the tail and wing tips, as it was destined for service in Alaska.
It was assigned to the Arctic Test Center, Fort Greely,AK and delivered from Downsview to Fort Greely. It continued to serve there until October 1959 and 53296 departed to Fort Richardson, Anchorage, where it was assigned to the 568th Transportation Company as a support aircraft.
In June 1961 the 568th Transportation Company moved to Fort Wainright near Fairbanks, soon after the Army took over Ladd Air Force Base and re-named it Fort Jonathan M. Wainright.
53296 was destined to serve with the 568th TC for many years. At some stage during the 1960s, the paint scheme was removed and from then on it was flown in its natural metal finish with red tail and wing tips and was named the 'Silver Salmon'.

In July 1972 the Otter was transferred from the 568th TC to the 12th Aviation Company, also at Fort Wainright.. On 21Jun73 the 12th Aviation Company was formally inactivated in a ceremony at Fort Wainright.
The Otter would continue to have a military involvement.
It was transferred to the University of Alaska, Fairbanks registered N90422, but operated in support of the Naval Arctic Research Laboratory (NARL).
The NARL had been established in 1947, located on the shore of the Chukchi Sea between Point Barrow and the village of Barrow, the largest Eskimo settlement in North America.
To accomplish its mission, the University of Alaska operated a fleet of aircraft for the NARL, including Douglas C-47s, C-117s, a Twin Otter, N90422 the single Otter and four Cessna 180s.
The Otter flew for the NARL for 14 years.
The NARL disposed of it in 1987. In June of that year, it was reg'd to the Interior and Arctic Alaska Aero Museum, and parked at their facility at the Fairbanks airport.
It was in a natural metal finish, named 'Miss Piggy'.

It remained in this retirement for 5 years, until June 1992, when it was registered to Douglas G. Solberg of Juneau, Alaska. This was in connection with its sale to Kenmore Air Harbor Inc to whom it was registered in Oct 1992 and it joined their fleet based at Kenmore in Seattle after re-build & repaint into the company colours.
As with the other Kenmore Otters, it was converted to a Vazar turbine Otter.
During 2001 it was flown with EXPEDIA.COM billboard titles. For summer 2003 its 'logo' colour scheme was for Victoria, BC's Butchart Gardens '100 years in bloom'. Victoria is one of the destinations it serves on its commuter services for Kenmore Air. It retained this 'Butchart Gardens' logo colour scheme during 2004.

But these days we see it back in Kenmore's own smart livery.

(Continued from above)

... In December 1972, Jack Lysdale, in whose hangar at Fleming Field in South St. Paul, MN the aircraft had been stored, obtained ownership. Lysdale made the decision to restore the Hamilton to 100% airworthiness. To do this it was necessary to completely disassemble the aircraft which nullified previous restoration efforts.
After taxi tests were made, the first flight of the restored aircraft was made on August 12, 1975. That
same month it was displayed at the Blakesburg, IA Antique Fly-in where it took five first place honors including Grand Champion.
Hamilton NC879H is the only surviving airworthy Hamilton in existence.
It received meticulous restoration, and it has been hangared at Fleming Field, South St. Paul, MN since its last flight on 12Jun78. The aircraft logbook shows it has accumulated 46.25 hours in addition to the 5183.5 hours prior to restoration.

Note: the FAA website showed (check date 21Apr2015) NC879H was reg'd 31Jul2014 to Pole Pass Airways LLC.

History of c/n 106 from Karl E. Hayes' monograph on the deHavilland Otter (text abbreviated by Webmaster)

Otter 106 was delivered to the United States Army on 11th May 1956 with serial 55-3262 (tail number 53262). By January 1962 it had been transferred to Fort Eustis,VA to the Army Transportation School, where it was iused for ground instructional technical training).
It continued under this designation until May 1973 when it was put up for disposal as military surplus. It was however to languish at Fort Eustis for another five years before it was sold.
Parts were damaged including holes in the fuselage and many parts (and instruments) missing including flaps, one seat and all glass; airframe and engine hours unknown; data plate and historical records not available.

The purchaser of the Otter was William H. Magie, whose company was Wilderness Wings Airways of Ely, Minnesota to whom the Otter was registered as N90627.
Despite its evidently poor condition, the Otter was rebuilt and entered service with Wilderness Wings Airways alongside its other Otter N432GR (179), serving the bush country of northeast Minnesota.
The Superior National Forest extends north of Ely, up to the Canadian border with Ontario. The company also flew a Beaver (N11015), a Queen Air and Beech 18. However, it ceased operations in 1983. In March 1984 the Otter was registered to Richard T.Riley of Allston, Massachussets.
In May 1987 N90627 was sold to Red Baron Leasing Inc of Anchorage, Alaska a leasing company which owned a number of Otters.

That month, the float equipped Otter was being ferried from Owen Sound, Ontario to Anchorage.
In the course of the long ferry flight, N90627 stopped at Selkirk, Manitoba to refuel and for crew rest.
As the Otter taxied away from the dock on 11May87 to resume its delivery flight, the engine stopped and the pilot attempted a re-start. During the re-start the engine caught fire and the crew abandoned the aircraft, which then drifted to the shoreline of an island. The fire subsequently subsided, after causing extensive damage. The engine had been replaced in Owen Sound, and the aircraft had flown ten hours since then without any problems.
The damage was repaired and the Otter eventually completed its delivery flight to Anchorage, where it was re-registered N666XX.

It flew for Sound Adventures Air Service Inc on lease from Red Baron Leasing for nearly 2 years, based at Lake Hood. In April 1989 it was re-registered N888XX to Red Baron Leasing Inc.
In June 1989 it was sold to Ketchum Air Service, also based at Lake Hood beside the Anchorage International Airport.
It was flown down to Vancouver where it arrived on 12Dec89 and it was converted to a Vazar turbine Otter at the Aero Flite Industries facility in Vancouver during the early months of 1990.
It was complete by 06April1990 and re-registered N888KA on 29Apr90 and entered service with Ketchum Air, looking pristine after its complete overhaul and re-engining. It was used for the for the most part to fly hunters, fishermen and tourists during the summer months. It flew for Ketchum Air without incident until 20Aug99 when a mishap occurred.
The Otter, with one pilot and three passengers on board, was taking off from an un-named lake about 30 miles west of Port Alsworth, Alaska. Due incorrect setting of the flaps it failed to get airborne.
N888KA struck the 4 feet high bank at the end of the lake. The floats separated from the fuselage, which remained upright and slid about 100 feet across rough tundra. Substantial damage was sustained to both wings and horizontal stabilizers and the underside of the fuselage. The four on board were uninjured.
This accident ended the Otter's career with Ketchum Air.

The insurers offered the wreck to Kenmore Air Harbor, who decided to purchase it for rebuild. It was airlifted by helicopter from the crash site to the small airstrip at Nondalton on Lake Clark. It was then shipped by barge 20 miles or so to the airfield at Port Alsworth and flown from there to Anchorage on board a Lynden Air Cargo Hercules. It was then shipped in a container to Kenmore's base at Seattle for rebuild.
N888KA was registered to Kenmore Air Harbor Inc on 20Sep99.
In December 2000 the damaged Otter was noted in the hangar of Kal Air Repair Ltd at Vernon, BC, awaiting repair. Kenmore Air had contracted out the rebuild of the Otter to Kal Air, who would also fit large scenic windows to the aircraft.
Following completion of the rebuild, the Otter was flown to Paine Field, Seattle for painting into Kenmore Air Harbor's yellow and white colour scheme. It was re-registered to the company on 26th March 2002 as N707KA and named 'Capt.Greg Munro'.
It entered service with Kenmore Air as part of its large fleet of turbine Otters.
It was exhibited at the Otter's 50th birthday celebrations held in Victoria, BC in Oct.2002.

History of c/n 11 from Karl E. Hayes' monograph on the deHavilland Otter (text abbreviated by Webmaster)

Otter number 11 was delivered to the RCAF with serial 3665 on 01Apr1953. Its first posting was to 408 Squadron, Rockcliffe where the unit history records its early days occupied with local area flights, pilot training, cross countries and water training at Golden Lake.
In June '53 3665 flew north and spent that summer based out of Goose Bay, Labrador and Knob Lake, Schefferville, Quebec, supporting the squadron's mapping and surveying tasks. Other assignments followed. The unit was one of the most active rescue units in the RCAF.

In Feb. 1962 it was retired from service. It remained in storage for a year, until as one of five Otters which were donated by the Canadian Government to the Government of India, to whom the Otter was formally transferred on 24Apr1963.
The five Otters were shipped to India, where 3665 took Indian Air Force serial BM-1003. For the
next 27 years it was to serve in India. Nothing is known of its Indian Air Force service, other than it was with 41 Squadron based at Palam Air Base, New Delhi between 1976 and 1980.
It was advertised for sale in April 1993 by the Indian Ministry of Defence. The successful purchasers were La Ronge Aviation/Mike Hackman Aircraft Sales, it had 5,882 hours on the airframe. Eight were shipped from Calcutta and had arrived at Saskatoon, Saskatchewan by 30th April 1994. They were then advertised for sale.

The purchaser of Otter c/n 11 was Kenmore Air Harbor Inc of Seattle.
The Otter was trucked from Saskatoon to the company's base at Kenmore, on the northern end of Lake Washington and was registered to its new owners in May 1995 as N8262V. It was one of three former Indian Air Force Otters acquired by Kenmore, the others being c/n 37 and c/n 221. These 3 Otters were rebuilt by Kenmore Air and during the re-building converted to turbine power with the installation of PT-6 engines.
Thus completed, Otter c/n 11 was re-registered N87KA on 23Jul96 (FAA website now states N87KA reg'd 10May95 to Kenmore Air -Webmaster), and painted in Kenmore's smart yellow and white trim, joined the company's expanding fleet of turbine Otters, used on scheduled and charter services in the Puget Sound area and also the Inside Passage.

For the winter of 2000/01 N87KA, together with N50KA (221) went on charter to Island Seaplanes of Nassau in the Bahamas, before resuming its commuter services from Kenmore.
In 2003 Kenmore Air introduced a Cessna 208 Caravan amphibian into the fleet, joining its Beavers and turbine Otters. The Caravan was used to introduce landplane service to Bayview and Port Angeles. The following year, in March 2004, two of the turbine Otters were advertised for sale, one of which was N87KA.
The Otter however continued in service with Kenmore Air pending a sale, though obviously Kenmore Air had a change of heart!
