Metalfatigue isn’t a subject that usually keeps me awake at night. For most of the 30-odd yearsduring which I’ve been an aircraft owner, I figured it was a subject of interest mainly tometallurgists and aeronautical engineers and other Ph.D. types, not to mere mortalaircraft owners like me. Figure 1 — Under dye penetrant, the fatigue […]

Winteris finally getting a grip here at the virtual airport. Airplane owners aresniffing the air and have set up engine heaters. Lots of hangars have airplanesplugged into wall sockets, as owners hope their steeds will start on the coldmornings without damaging the engine. The regulars here at the Lounge arestarting to look forward to our […]

On July 13, 1999, the Florida State Attorney’s Office brought criminal charges against SabreTech, Inc. because of the 1996 ValuJet DC-9 disaster. The state prosecutor’s charges include 110 counts of third-degree murder and manslaughter under Florida law against SabreTech, Inc. Apparently no state criminal charges have been filed against any of the executives or employees […]

We were about a hundred and fifty feet from touchdown and to have a landinggear come through your windshield and the windshield come flying into your lapis kind of a strange sensation. The airplane on top didn’t really push us downthat […]

Inwriting this article, I am reminded of the often-used patter by younginstructors in which the student is told to keep an eye on the enginetemperatures and pressures during the takeoff. The reality is that oil andcylinder head temperatures are slow to indicate trouble, while oil pressureneedles can flicker and vary by small amounts depending on […]

Growing up in North Dakota, she and her brother spent much oftheir spare time at local airports and began a scrapbook of aviation photos and newsclips. When Eleanor was 14, the family moved from the midwest to Long Beach, Calif. Therethey found a mecca for […]

Aletter from a reader who had an unpleasant experience at a non-towered airportprompted this column. He wrote the following account: I was recently making a straight-in final to a non-towered airport. Monitoring the Unicom frequency, I was aware of another airplane in the pattern flying touch-and-goes with a student. Since I was approaching from the […]

The constant-speed version of the bootstrap approach isin some ways less complicated than the fixed-pitch version. Preliminary flight tests forconstant-speed airplanes (to obtain some of the nine “Bootstrap Data Plate”numbers) require only glides, no climbs. And partial-throttle operations forconstant-speed airplanes are automatically included from the get-go. On the other hand, the constant-speed propeller thrust model […]

Okay,folks. This nonsense has gone far enough. It’s one thing when a handful of self-appointed Y2K consultants and gurus hang outtheir shingles and their web sites to take advantage of the gullible and panic-prone. Orwhen a few thousand survivalist whackos announce plans to spend their 1999 Christmasvacations fleeing from civilization and holing up in the […]
