After serving with the Fuji Detachment in Japan I returned to H&MS-36 in Okinawa. Here my primary duty was as a PMIP (Post Maintenance Inspection Pilot) on CH-46s. Every time maintenance is done on an aircraft a PMIP must flight test the bird and sign it off before it can be assigned back to the regular flight schedule.
Over the next weeks the aircraft were checked over as best they could be to prepare them for a five hour over-water flight to the southern tip of Japan. As a test pilot I lead at least three two-bird flights from Okinawa to Atsugi Japan where they would undergo major overhaul. We would then fly repaired helicopters back to Okinawa. We worked very closely with the weather-guessers to choose a day where the winds would be favorable. We joked that the weather prognosticators could not even predict rain if they looked out the window and saw it raining. However, they gave us very detailed wind estimates for various altitudes. It was the command pilot's decision when to go. The flights were done by dead-reckoning (SWAG) because at our low altitude we could pick up no navigational aids. The aircraft were loaded with two huge auxiliary internal fuel tanks that, with luck and good winds, would provide us adequate fuel to reach a Japanese base at the Southern tip of Japan.

One time we landed with less than 15 minutes fuel remaining! The tough part of these flights was we could not smoke with the internal tanks on board and we were COLD - flying in the winter with no heat, missing windows wearing summer flight suits!
After a layover at MCAS Iwakuni, we topped off our tanks and flew East - turning North around Mt Fuji to land at Atsugi about 10 miles inland from Yokohama. We turned over the aircraft to NIPPI, the Japanese Contractor doing heavy overhaul work for FAWPRA: Fleet Air Wing Pacific Rework Activity.
After "cheating death" on at least 3 of these round trips I was transferred to Atsugi to be a test pilot working with NIPPI (Nippon Aircraft Corporation) as they overhauled Marine and Navy aircraft. This was an exciting job working with the Japanese mechanics testing the helicopters after they underwent total tear down and rebuild. These people did outstanding work. After a month an aircraft that looked like it should be headed to a junk yard rolled out of the factory looking brand new.

Our responsibility was to flight test them and make sure they flew like new! My sign-off was the official acceptance of the aircraft back to to the Marine Corps. It was an awesome responsibility and I made every effort to be sure everything was perfect because the lives of others would be held in the balance for years to come.
A month after leaving Atsugi and returning to the States I was shocked to hear about a horrible crash in one of the birds I had tested. The aircraft was air taxiing at Yokota Air Force base after picking up passengers. As it hover taxied in front of a Transport Airplane the CH-46 suddenly came apart, and self destructed in mid air, killing all on board. Evidently, a part in the rear transmission was installed improperly, the transmission seized, the rotors inter-meshed and that was all she wrote. Unfortunately this was something no amount of test flying could reveal.

My 13 month tour overseas was over. I had done some hairy mountain and over-water flying in Japan and Okinawa. I had learned the CH-46's workings as well as I new my own body. I understood the electrical systems, hydraulic systems, the engine parameters and the the balancing of rotor systems. I really loved the single pilot flying as a test pilot; the detail and accuracy required and the great responsibility I had been given. I may not have flown in Vietnam but I certainly had done my best to support the aircrews that did.
Little did I know that my next year at MCAS Cherry Point, North Carolina would be the exact opposite as I learned to fly the standard grey GI Mark One, Mod.2 desk..... I was pushing paper!
I did not like it
A year of administrative work prompted me to write my detailer at Headquarters Marine Corps and ask for an "early out". I asked to leave the Marine Corps early before my regular 3 years would be up!
Stay tuned - the best was yet to come.
