After the air combat simulation accident involving a Beech T-34, the FAA issued an AD limiting the airplanes aerobatic flight. As part of the investigation into the accident, the FAA has determined that a number of T-34s have been imported into the United States that have been sufficiently modified so that they no longer meet the original type design.

Over the years since the aircraft was originally produced, many of them have been exported and used by foreign governments for military missions or…

Among pilots, the perception of whats safe is forever clouded by the tree-falling-in-the-woods syndrome. If no ones there to hear it, does it still make a thud?

The aviation safety corollary has to be the accident stats numbers game. When a trend seems to surface, was it there all along or are we just noticing it because we happened to be looking?

Such may very well be the case with the FAAs current safety problem child – runway incursions. According to data collected by the agency, runway incursions are at an all-time high and rising.

Worse, most of them are committed by general aviation pilots, giving the impression that the average Bonanza or Piper owner is bumbling around…

Following on the heels of an airworthiness directive and an earlier warning about aerobatic flight, the FAA is continuing its investigation into fatigue on T-34s used in air combat simulation.

After the April 1999 accident that followed the in-flight wing separation of a T-34A Mentor, a metallurgic examination found structural fatigue cracks at several of the fracture surfaces. An examination of the left wing, which did not separate from the airplane, also displayed fatigue…

Jan. 2, Telluride, Colo.
Cessna Golden Eagle
At approximately 09:50 MST, a Cessna 421B crashed while maneuvering near Telluride. IMC prevailed but the pilot was not instrument rated and had not filed a flight plan. The flight had departed Montrose, Colo., approximately 30 minutes before the accident, en route to El Paso, Texas….

American General AA-5A Cheetah
Poor Engine Performance
The aircraft owner reported the engine performance deteriorated during flight.A mechanic discovered the carburetor bowl was not attached tightly to the throttle body. Even though the locking-tab washers under the attachment screws were properly installed, the screws were loose. The gasket may have shrunk or the attachment screws were not properly tightened during installation, allowing excessive air to be dr…

A fairly new private pilot recently mentioned that hes read about stalls occurring while turning from base to final but doesnt remember hearing much discussion about it during his private pilot training.

The pilot had done all the approach-to-stall, stall recognition and stall recovery training required to perform the tasks required by his certificate. However, he had no idea why he was doing them – other than to pass the checkride – nor how he might apply this training in the real world.

The central concept never presented to him is that the main reason for stall training, including the spin discussions (which replace the mandatory spin training of the old hairy-chested days), is…

The FAA has approved Exxon Aviation Oil Elite 20W-50 for use in Lycoming O-320-H and O-360-E series engines as fulfilling the requirements of AD 80-04-03R2 – making it the third oil approved as an alternative method of compliance.

The AD was aimed at preventing excessive wear and oil contamination due to spalling of the hydraulic lifters. It requires operators to add a Lycoming-approved oil additive at each 50-hour oil change. In 1987, the FAA determined that Aeroshell Oil W…

I enjoyed Wally Millers article Big Pile of Trouble [Weather Tactics, June], but I was sorry to see that he did not list my favorite pre-flight planning guideline and flying technique for handling wind and the mountains. At my flying club in Seattle, they teach us to plan for at least 1,000 feet of ridge clearance for each 10 mph of wind at altitude. If your airplane cannot fly at that altitude, take a different one (we have a pressurized Centurion) or do not go. Following this guideline does not assure that you will stay out of trouble – as pointed out in Millers article – but it does give the pilot a minimum altitude to fly and reasonable basis for a go/no-go decision.

July 1, Spanish Fork, Utah
Diamond Katana C-1
At 13:29 mountain time, a Diamond 20C-1 lost its propeller in flight near Spanish Fork, Utah. The pilot and passenger were not injured. The pilot said that he was on a local flight and returning to Provo, Utah, when the propeller separated from the airplane. The airplane was at 9,500 fee…
