Vacuum pump failure fatal for three - General Aviation News

May 25, 2018 · The instrument-rated pilot was conducting a personal cross-county flight and was operating on an instrument flight rules flight plan. While he was flying in visual conditions between cloud layers at 7,000′ and heading toward the destination airport, he reported to air traffic control that the Beech V35 had experienced a vacuum pump failure and that [.]

The death knell for the vacuum pump? | Air Facts Journal

Apr 12, 2017 · For the last 50 years, the dry vacuum pump has been at the heart of the instrument panel, driving the attitude indicator and often the directional gyro as well. While inexpensive and compact, such pumps literally operate in a constant state of self-destruction, as the carbon vanes wear away to lubricate the pump.

Handling a Vacuum System Failure - AVweb

Joe's failure was a total vacuum system failure caused by shearing of the shaft of the vacuum pump. Although this is a very common failure, it is not by any means the only way the vacuum system can let you down. (See Scott Purdy's excellent article on failure of the vacuum system components.) However, beyond the vacuum pumps and associated .

You Just Lost Your Only Attitude Indicator In IMC.Now .

Some aircraft have vacuum powered attitude indicators and electrical heading indicators. In others, both the attitude and heading indicators are vacuum powered. If they're both vacuum powered, your vacuum system could have failed - and the heading indicator is also unreliable. Don't trust the heading indicator until you've verified it's fine.

Mar 15, 2016 · Great observations guys. Yes the cable passing close to the vacuum pump is the throttle (RPM) cable. The photo is somewhat deceptive in that there is actually 1/2" between both vacuum pump tubes and the cable. I had to leave early Sunday before finishing up .

gyroscopic systems and instruments

vacuum power system: Air-driven gyros normally are powered by a vacuum pump attached to and driven by the engine. Suction lines connect the pump to the instruments, drawing cabin air through the filtered openings in the instrument case. As the air enters the case, it is accelerated and directed against small "buckets" cast into the gyro wheel.

Understanding Gyroscopic Instruments - AOPA

In the event of a vacuum pump failure, debris will not be scattered through the system and deposited into expensive, sensitive instruments. There is a filter inside the cabin that removes particulates from the air going into the gyros.
