Aircraft Landing Gear Failures

Recently we have seen a string of aircraft landing gear failures where aircraft have come in with one of the landing gear in an inappropriate position, turned side ways or only half way down. There was an Airbus, which landed and sent sparks flying on its nose gear at LAX. The Nike Gulfstream had an issue and luckily the service department at the Gulfstream Corporation was able to get on the horn and figure it out in-flight. There was a King Air which recently landed on its belly in the South and about 14 other not so notable but serious incidents in the last year. None of these incidents or accidents caused loss of life, yet one has to wonder if they maybe connected in some way? I believe they are and some may call this a routine conspiracy theory, yet it appears to this pilot that they are all in fact related. How so you ask?

Well let me explain my understanding of the matter and some recent aviation changes, which are in question. First all landing gears use hydraulics and hydraulics require fluid. All the aircraft, which had the problems use hydraulic fluid and are capable of flying above 12,500 feet. That is the point pressurization is necessary and required in aircraft unless you have oxygen masks onboard for the pilots. Temperature decreases at approximately two-degrees per thousand feet. On a cold day it is even colder up where these aircraft fly.

The FAA made some changes due to the EPA
