Narrative:

Passenger load was given to the captain prior to leaving operations which showed 8 people based on this flight. The aircraft was fueled to 1400 pounds. 17 passenger actually boarded the aircraft. Among the 17 passenger was a 1/2 weight child. Computed takeoff weight on the manifest was 14085#. Planned fuel burn to sle, 200#, for a landing weight of 13885# at sle. 2 passenger and child deplaned at sle with 3 bags. No passenger or cargo were added. After landing at otm noticed 1 lot of cargo weighed 284#. Checked bag count, found 25 bags on board, plus 312# of freight. Pdx manifest showed 22 bags and 199# of freight. Pdx bag count should have been 28 bags. After recomputing weights found the following: pdx bag count 6 bags short (147#). Freight weight shown on manifest was 113# under actual weight on aircraft. Total error on manifest was 260#. Actual takeoff weight at pdx was 14345#. Actual fuel burn to sle was 230#. Landing weight at sle, 14115#. Maximum landing weight for the aircraft, 14000#. Problem could be remedied by more accurate bag counts by station personnel and insure that changes are given and noted by the person preparing the manifest.

Title: ACR SMT OVERWEIGHT LNDG DUE TO INACCURATE LOAD MANIFEST.

Narrative: PAX LOAD WAS GIVEN TO THE CAPT PRIOR TO LEAVING OPS WHICH SHOWED 8 PEOPLE BASED ON THIS FLT. THE ACFT WAS FUELED TO 1400 LBS. 17 PAX ACTUALLY BOARDED THE ACFT. AMONG THE 17 PAX WAS A 1/2 WT CHILD. COMPUTED TKOF WT ON THE MANIFEST WAS 14085#. PLANNED FUEL BURN TO SLE, 200#, FOR A LNDG WT OF 13885# AT SLE. 2 PAX AND CHILD DEPLANED AT SLE WITH 3 BAGS. NO PAX OR CARGO WERE ADDED. AFTER LNDG AT OTM NOTICED 1 LOT OF CARGO WEIGHED 284#. CHKED BAG COUNT, FOUND 25 BAGS ON BOARD, PLUS 312# OF FREIGHT. PDX MANIFEST SHOWED 22 BAGS AND 199# OF FREIGHT. PDX BAG COUNT SHOULD HAVE BEEN 28 BAGS. AFTER RECOMPUTING WTS FOUND THE FOLLOWING: PDX BAG COUNT 6 BAGS SHORT (147#). FREIGHT WT SHOWN ON MANIFEST WAS 113# UNDER ACTUAL WT ON ACFT. TOTAL ERROR ON MANIFEST WAS 260#. ACTUAL TKOF WT AT PDX WAS 14345#. ACTUAL FUEL BURN TO SLE WAS 230#. LNDG WT AT SLE, 14115#. MAX LNDG WT FOR THE ACFT, 14000#. PROB COULD BE REMEDIED BY MORE ACCURATE BAG COUNTS BY STATION PERSONNEL AND INSURE THAT CHANGES ARE GIVEN AND NOTED BY THE PERSON PREPARING THE MANIFEST.
