A customer called to say his R/H generator went offline mid-flight. He happened to have an F90, but this squawk could happen with any King Air. For troubleshooting purposes, I suggested he swap the generator control units to see if the problem went to the other side, and it did. I had an exchange GCU…
Years ago, a King Air 200 was in a shop for phase inspections and the owner was waiting for it to be released. It was the first phase inspection since he had purchased the aircraft. Unfortunately, the shop found both engines would not make book power – they temped out before reaching max torque –…
Let’s talk about your preflight routine. Did you know there are some simple tasks you can add to your preflight checklist that could ultimately save you thousands of dollars in maintenance costs? Your flaps are one example—do you check your flaps regularly? Remember the old adage: “An ounce of prevention is worth a pound of…
Recently, hot weather has been a top news story all over the United States. Areas that don’t normally see triple-digit temperatures have been getting a taste of what we deal with every summer in the desert Southwest. This got me thinking about an engine problem that can crop up when the OAT is scorching hot.…
Take a look at the wheel bearing in Figure 1 (below) – it’s dry as a bone – there’s not a speck of grease or lubrication to be found. It looks like it sat in a solvent tank for a month, then tossed on a junk pile. The crazy thing is this wheel bearing came…
Imagine you are pre-flighting your King Air, checking the oil and on one engine the oil is off the stick! What do you do? For many, the first instinct is to dump a couple quarts in that side and check the stick again. Just make sure you have plenty of rags in the aircraft because…
I’ve been corresponding with a King Air owner about an oil temp problem he has wrestled with for awhile. On one engine, the oil temp is not warming up to where it should be. Initially he worried about icing in the oil-to-fuel heater, but we have since ruled that out. This started my thinking about…
A director of maintenance from Alaska with several King Air B100s called me not long ago. The most recent addition to his fleet had a pressurization problem that would not resolve. The system tested fine on the ground, but there was no pressurization in the air. He had researched the part number of the flow…
I spend a lot of time researching logbooks on behalf of buyers considering King Airs for purchase. They need to know where the aircraft is maintenance-wise. Some of these King Airs are “younger” but many have 10,000 hours or more. The longevity of the Beechcraft King Air makes me proud, but 10,000 hours makes for…
If you hit the starter switch in your King Air and nothing happens, or if you get a “gen out” light while in flight, starter generators will become top of mind. Generally speaking though, starter generators are not too problematic in most King Airs. The notable exception is the “Infamous -001” found in King Air…
