Preparing for writing the next blog is an interesting
task (most of the time). Lately I have been made aware of so many accidents
related either to the take-off or landing phases of flight, that I started to
read about the landing and take-off processes.* This a wonderfully written
article, with many superb illustrations, both diagrammatic and photographic. Not
only are details of the various types of gear given, but also the problems
related to the take-off and landing processes and their relationship to the
landing gear.
The illustrations are just fabulous. Details of the
simplest brake systems, with just one disc rotor to multiple disc systems used
on large aircraft. Discussions include complicated things as anti-skid systems
for airliners, not something a small plane pilot need worry about. But what is
valuable is the discussion of the
testing of brakes and brake systems for small and large planes. This
includes checking brake fluid and the subsequent addition of
fluid if more is needed. The replacement of brake linings is covered, as well
as brake adjustment.
Finally, tires are fully discussed. This includes the
various types, as well as inflation procedures and pressures. Complete
assessment of aircraft tires is covered as well as “how to do it”. This
includes tire inflation, tread inspections and repairs if needed. The article
ends with how to protect your airplanes tires during taxiing, take-off and
landing.
In summary: This
article is excellent reading for any pilot, but especially for those doing some
of their own maintenance
This all brings to mind an incident from years ago when I
was happily and nonchalantly flying around the Boston area in an old J-3 Cub.
The weather was warm and the side window flaps were up, offering the best
visibility of everything out there and wonderful “air conditioning”. As I had
been flying for about an hour, and the fuel dip stick was getting low, I
decided to head back to Tew- Mac field, North of Boston. (This airfield has
since been closed.) As I was looking down
at something of interest on the ground, three hundred feet below, I happened to
see something funny on the top of the right tire. There seemed to be a cut in
the tire, which looked like a small flap of rubber. Oh-oh I said to myself and decided that the
landing had better be gentle. A blow out would not be fun, and would probably
lead to an unplanned 360 degree turn and possible roll over. I decided to land
as gently as possible on the right main and hope for the best. Well, happily it
turned out fine. The tire didn’t go flat and was replaced.
So, pay attention to your landing gear and all associated
systems. Do this both in pre-flight and
post-flight. If you can do so while in flight, so much the better. Have fun up
there, but do look around.
