Narrative:

Upon rotation in an unusually high attitude (aft C.G. Situation), I realized that aircraft cargo was improperly loaded. The cargo imbalance was due because of uneducated ground personnel (with regard to aircraft limitations), relatively inexperienced first officer, his failure to be aware of aircraft limitations, the captain's complacency with regard to his failure to double check weight and balance data (load manifest). The complacency is partially due to current contractual disputes with the carrier, and extreme boredom flying the same routes and being overworked this week (fifth day in a row). The most important factor contributing to this situation is the operation of 2 different aircraft with a common type rating, e.g., this flight crew almost always operates an light transport model B, which has a higher gross weight, higher limitations for cargo bin weights, etc. This occurrence of improper C.G., and exceeding the weight limits of the cargo bins happened in an light transport model a, which has lower associated weight limits. I believe cargo bin weight limits should be placarded in the cockpit.

Title: ACR LTT CARGO LOADED IMPROPERLY RESULTING AN AFT CG EXCEEDING LIMITS.

Narrative: UPON ROTATION IN AN UNUSUALLY HIGH ATTITUDE (AFT C.G. SITUATION), I REALIZED THAT ACFT CARGO WAS IMPROPERLY LOADED. THE CARGO IMBALANCE WAS DUE BECAUSE OF UNEDUCATED GND PERSONNEL (WITH REGARD TO ACFT LIMITATIONS), RELATIVELY INEXPERIENCED F/O, HIS FAILURE TO BE AWARE OF ACFT LIMITATIONS, THE CAPT'S COMPLACENCY WITH REGARD TO HIS FAILURE TO DOUBLE CHK WT AND BALANCE DATA (LOAD MANIFEST). THE COMPLACENCY IS PARTIALLY DUE TO CURRENT CONTRACTUAL DISPUTES WITH THE CARRIER, AND EXTREME BOREDOM FLYING THE SAME ROUTES AND BEING OVERWORKED THIS WEEK (FIFTH DAY IN A ROW). THE MOST IMPORTANT FACTOR CONTRIBUTING TO THIS SITUATION IS THE OPERATION OF 2 DIFFERENT ACFT WITH A COMMON TYPE RATING, E.G., THIS FLT CREW ALMOST ALWAYS OPERATES AN LTT MODEL B, WHICH HAS A HIGHER GROSS WT, HIGHER LIMITATIONS FOR CARGO BIN WTS, ETC. THIS OCCURRENCE OF IMPROPER C.G., AND EXCEEDING THE WT LIMITS OF THE CARGO BINS HAPPENED IN AN LTT MODEL A, WHICH HAS LOWER ASSOCIATED WT LIMITS. I BELIEVE CARGO BIN WT LIMITS SHOULD BE PLACARDED IN THE COCKPIT.
