Inspection time

Since most of my aviation friends have had to suffer through many long blogs of a variety of topics, I thought this time we could share a bit more of aircraft specific information.The PAC 750XL with a PT6-34 engine of 750 SHP is proving to be a simple and reliable workhorse in the utility role. The factory maintenance program is set up on 150 hour intervals. It generally makes it through between inspections without any major squawks. In this environment (operating from wet and muddy airstrips) we keep it washed on a daily basis, and compressor rinse weekly or on return from a coastal operation. The aircraft is approaching 2,000 hours since new.

A few latches and four camlock fasteners at the firewall and the top cowling comes off. A half dozen screws on each side at the firewall and a couple of hook latches on turnbuckles and the entire lower cowling comes off easily in a single piece. This gives great access for working on the engine.

As you can see, it’s a pretty clean and straightforward installation. That’s the battery box at top center of firewall, generator control box, electrical relay box, then main fuel inlet and filter along with EPA can at the bottom LH side.

And on the right hand side you have the brake master reservoir, oil cooler, and bleed air conduit for cabin heat.

This time it was due a fuel nozzle inspection.

Pacific Helicopters next door have a nice overhaul facility where they can do our nozzle flow checks, inspection, and testing for us.

Here Linden Millist is helping with the borescope inspection on the hot section.

Not much under the cabin floor other than a couple of fuel line interconnections and the flap motor. The flap system uses a torque tube interconnecting both sides driven with a single motor.Notice the nice flat floor with brown line track and large rubber bumper along the door sill. If you look close you can also see the brown line track running down each cabin side. This makes it easy to load and use tie down straps almost anywhere to secure cargo. The passenger seats also fold to stow either in the aft cargo area beyond the door or in the belly pod.

Here I’m inspecting and lubricating the electric elevator trim system. I’ll let you guess what the boxes are mounted on fuselage side?

I’m a lucky guy to have a wife who is not only willing to live halfway around the world with me, but also lends a hand to help out wherever needed. Here Bonnie is doing some paint touchup work.

And a final cleaning of the cockpit and windshields at the end of the inspection.
So what does the beast fly like? Stay tuned for a future episode.

Empty Nest

On August 4 our girls boarded the Air Niugini flight for their trip back to the USA and Union college.


Dad was stoic while Mom shed bitter tears! For me, one of the greatest sacrifices of being a missionary is the separation from those you love. It never gets easier. But I thank God for providing the means and ability to bring them home this summer. While the time passed way to quickly, it was a summer packed full of wonderful memories.

All was not fun and games. Their cheerful willingness to help wherever needed (from chemically cleaning steel beams to designing a Web site) made them a blessing to the AAS team as well.

Thank you girls. You are sorely missed!
