Mazda's Big Ambitions For CX-5 Diesel

Yes and ummmmm...no.  Yes.   Metal fatigue is a very real thing in aviation.  Its more about how many times the sheet metal has expanded and contracted  under stress rather than the age of the airplane itself.  10 years is somewhat too young for an airplane to be retired as airplanes are engineered fly double and even triple that age.  Unless of course the airplane in question has taken off, flown and landed enough times that would equal its maximum lifespan in 10 years.   This latest accident, UPS had a 34 year old McDonnel-Douglas MD-11 flying around.  Now...at 34 years of age, this airplane should been of concern... yes.   Like I said, airplanes' lifespans reach 30 years.  Sometimes more than that if maintenance is done properly and rigorously.   Using google and Wikipedia, if fact, 2 months prior, the airplane in question HAD been grounded for 6 weeks because cracks were found in the fuel tanks. Corrosion was also found in the structural beams in its fuselage. Repairs were made.  However, with airplanes, age is not a criteria for maintenance. But hours of flight and "cycles".   A cycle is 1 take-off and 1 landing sequence.  The airplane had logged 21000 and change cycles and the maintenance threshold for what had ultimately failed in the airplane was not due until 28 000 and 29 000 cycles.  Now...at 34 years old, maybe more vigilance was needed... This is how the airplane safety industry works. It takes an accident to amend and/or instate new safety regulations.  Maybe with this accident, NTSB will implement an age criteria too alongside flight hours and cycles.  At age 30 and a more rigorous inspection is to happen and not rely solely on cycles and flight hours.    https://en.wikipedia.org/wiki/UPS_Airlines_Flight_2976 The aircraft, N259UP, was a 34-year-old McDonnell Douglas MD-11F with manufacturer serial number 48417. The aircraft was first delivered to Thai Airways International in 1991 with the registration HS-TME,[7] after which it was converted to a cargo aircraft and delivered to UPS Airlines in 2006. It had flown 21,043 cycles and for about 92,992 hours,[8] and was equipped with three General Electric CF6-80C2D1F engines.[9][10][11] The last visual inspections of the left pylon aft mount were performed in October 2021. More rigorous "Special Detailed Inspections" for the mount lugs and wing clevis were not yet due, as the aircraft's 21,043 accumulated cycles were well below the 28,000 and 29,200 cycle thresholds required for those checks. Two months before the crash, it had been grounded for six weeks to repair a cracked fuel tank, and corrosion was later found along two structural beams in the fuselage. The aircraft re-entered service a few weeks before the crash.[12]
