in accordance with

“imaginary VERTICAL plane which all HORIZONTAL measurements are taken” •chosen by manufacture

used for VERTICAL reference on the aircraft •run the LENGTH of the aircraft, measured from ZERO line set by manufacture anything above zero line is positive water line anything below the zero line is negative waterline

LBL/ RBL “locations left or right of fuesalge center line”

“aid maintenance planning, divided into easily identified areas” •simply way to identify access doors and panels

REF from buttline 0 in the aircraft 1. measured from the buttock line or center line of the top or bottom of the fuselage 2. “they run along the LONGITUDINAL axis of the aircraft OUTWARD along the wing” 3. indicate the distance of a point on the wing from the center line of the aircraft

airbus = MM (metric) Boeing = inch’s (imperial)

1. code # given to manufacture 2. code # is referenced in parts lists Manufacturers codes referenced in the parts lists and their equivalent manufacturers name and addresses are provided within the list

1. a key reference document specific to aircraft type 2. describes in detail every component 3. shows relationship of 1 part to another

tail assembly “structure at the rear of A/C that provides stability during flight”

aircraft main body section “holds crew, passengers, cargo”

upright wall within the fueselage of an aircraft

1. used to dissipate the loads from one frame to the next 2. attached to skin

rigid structure used to hold the aircraft engine in place •on fuselage or wing

housing seperate from the fuselage that holds the engines “a nacelle has extra functions of directing smooth airflow NOT into the turbine intake fan”

structural weather proof enclosure protects the radar / antenna located on nose of A/C

a structure whose primary function it to produce a smooth outline and reduce drag

W = width of the dent Y = depth of the dent width over depth, divide and see if number is greater than 30 = acceptable Use W/Y to determine if the dent is within limits If W/Y > 30 = within limits If W/Y < 30 = not within limits The dent must be smooth Sharp creases, gouges and cracks are not permitted Pulled or loose fasteners are not permitted
