there is an STC to swap in the A1D5 engine, so you get the 250 HP instead of the 235 HP. It can be done via an engine swap, or by changing the pistons in the 235 engine to those from the 250 engine,

Back to the original post- A landing light bolted to the nose gear does not ordinarily meet the definition of a major alteration, therefore it does not require a 337 if a few conditions are met. If the parts used in the alteration are genuine aircraft parts, and are optional for that make &...

Christianity made simple: At first, god was god. Then one day he made everything. I guess he made himself first, but I’m a little hazy on that point. Anyway, then he made a man from some dirt and water. God made the man look like himself, because he didn’t have any other specifications. Then...

request a block altitude to allow for "turbulence"

What is the tail number of the plane you trained in?

Basically, anything that bolts directly onto the engine is tracked in the engine log book.

A red tag is the opinion of the person inspecting that part, if they are using standards not called out by the maintenance manual for that part. Opinions may vary, unlike facts.

They are around. Which CFI did you train with? Each one is responsible for his own record keeping, in addition to the CTC.

The Orion is an amazing light, plus they are approved for your aircraft. The crap you see from Sextant is not.

Bob, I have recommended your CMEP book to folks for 15 years. It's the best book on multi-engine flying there is. Simple, precise, and effective.

The photographs of the blue tray with the resistance readings you see on the Busch article are mine. Champion changed their design with no fanfare almost a year ago. They quietly removed all reference to their old design, and the new design is not mentioned as "new and improved". It appears...

Mechanics can't declare a 20 year old, out of annual engine, removed from a junk airplane, airworthy without an inspection of some type. So install said engine on an airplane, and what do you have? An unairworthy engine, because it is out of annual, the airframe logbook does not cover it, and...

If you have a plane in annual, and with entries made in accordance with 91,417,a,1,for all the components listed "each engine, propeller, rotor, and appliance" are in annual, and then you remove one of them, and replace it with another, (that DOES NOT have an annual inspection entry in it's own...

It's not in 91.409. It's in 91.417, and other chapters, by backwards reference from FAA enforcement actions upheld by the NTSB. 91.417,a,1 requires records for the maintenance, alterations, and, 100 hour, progressive or annual inspections for each aircraft, engine, propeller, rotor, and...

If the IA signed each each airframe, engine, and propeller logbook with individual entries using the "airframe annual", "engine annual", and "propeller annual", then each of those has distinct annual sign offs and expirations. If he signed the airframe logbook with the phrase "aircraft annual"...

Shimmy is lateral acceleration caused primarily by loose parts, shake is vertical vibration caused solely by tire imbalance. Balance the tire assembly first. Then replace all the worn bolts and bushings. Your shimmy damper will have very little to do at this point, except do what it was...

Bendix mags with impulse couplings and Tempest fine wire plugs will cure it. You're going to throw away $1000 anyway on a 500 hour on the Slicks, and you will still have Slicks. And if you have Champion plugs older than June of 2014, those are a guaranteed failure point.

While those are the specs for operation, the manufacturing specs are more detailed. We have to follow existing data in FAA Advisory Circulars, or existing PMA specs. That is where beam spread, depth, and intensity are found. Glare and halation are addressed in the beam characteristics, and...

There is a difference between "peak recoverable oil" and "peak affordable oil". The first is based on available oil, which is not unlimited but we are getting ever more creative in finding and recovering it. The real problem is "peak affordable oil. We are already there. Oil is worth $40-70 per...

Landing lights have specific beam height and width specs that define the difference between the two different functions. Landing lights usually project a trapezoidal pattern about 12 degrees in width by 6 degrees tall. Taxi lamps will have 14-20 degrees of horizontal spread and 5-9 degrees...
