CLT accident
Well I didn't say that incorrect weights were the sole cause of the CLT accident. What I said was -
"These latest FAA weights were promulgated in 2004 after the crash of a commuter aircraft (a B1900 in Charlotte I believe) which was legal on paper but overloaded"
You may review the NTSB findings in their report DCA03MA022. The relevant portion is this:
The National Transportation Safety Board determines that the probable cause of this accident was the airplane’s loss of pitch control during takeoff. The loss of pitch control resulted from the incorrect rigging of the elevator control system compounded by the airplane’s aft center of gravity, which was substantially aft of the certified aft limit.
Contributing to the cause of the accident were (1) Air Midwest’s lack of oversight of the work being performed at the Huntington, West Virginia, maintenance station; (2) Air Midwest’s maintenance procedures and documentation; (3) Air Midwest’s weight and balance program at the time of the accident; (4) the Raytheon Aerospace quality assurance inspector’s failure to detect the incorrect rigging of the elevator control system; (5) the Federal Aviation Administration’s (FAA) average weight assumptions in its weight and balance program guidance at the time of the accident; and (6) the FAA’s lack of oversight of Air Midwest’s maintenance program and its weight and balance program.
So, no, it didn't have "everything to do with an elevator trim system rigged backwards, and nothing to do with the aircraft weight or balance" and yes, you are seriously mistaken.
