TECH REPORT

The contents below come from the magazine, Light Plane Maintenance, which I find to be an excellent resource for the maintenance and operation of aircraft. From this magazine, I will repeat the information and opinion of the author. 

Tire: Balance marking is either a red dot or triangle that identifies the light point of an aircraft tire.

Tube: The heavy point of the tube is usually marked with a red or yellow stripe and should be installed to align with the red marking on the tire. If no balance mark is evident on the tube, then the valve stem is considered to be the heavy point.

Once a tube is inflated in a tire, it will stretch up to 30%. The next time the tube is used when the tire is replaced; there is a greater risk of folding and pinching or thinning creating a weak spot. Goodyear says to not re-use a tube. New tires = new tubes too. (Of course it does if you are in the tire and tube business!)

For ease of letting the tube fit the tire, use tire talcum powder. Not the bathroom talcum powder.

At tire replacement, a pro- shop will strip the wheels of paint and use dye penetrant for a thorough check of the wheel condition, dress out any scratches and then re-paint.

Use heat resistant lock nuts for the thru bolts holding the wheel halves together. Heat build up can soften the nylon type and compromise the nut security.

Tires are made from natural rubber and are prone to damage if in contact with most any fluid but water. Do not use the Armor-All for the shiny look. This is detrimental to aircraft tires. (Though OK for the synthetic rubber car tires.)

Rule of Thumb for tire pressure. If inflated on the bench, use aircraft handbook recommended pressure. If inflated under load, with the full distributed load of the plane on the tires, add 4%.  

FLYING ADVENTURES

From Garnet West

Dave Renner wanted to pop down to the RV factory for some parts, so I offered to shift his CG a little aft–I read somewhere they fly better that way.An inversion layer kept conditions stable, but a slight headwind kept us from breaking the sound barrier, just loafing along at 180 knots!Initial climb hit 2k ft/min at 120 knots–I never did see where he hides the JATO bottles.I’m convinced that paint job makes air molecules move aside…What a ride!

AVIATION TRIVIA

This Aeronca  experimental prototype was quite a change from the Aeroncas we are familiar with. The major light plane builders were looking for a market resulting from all the pilots trained during World War 2.This plane was based on part from an Ercoupe design but did not use the familiar twin rudders the Ercoupe was noted for.The Quaker Cereal Company also produced a series of collector cardsincluded in the cereal boxes.  The Chum was one of those cards.
