each phase in the Phase manual, which sequences the inspection requirements task cards to be
performed. The sequence control card(s) shall be plotted from left to right, starting with the
personnel rating and number column, the prephase column, and continuing horizontally into the

conditioned air requirements shall indicate ON when required to complete the applicable tasks;
OFF when application of power or air would be dangerous to personnel or damaging to the

the QECA manual, which sequences the QECA inspection requirements for all airframe
applications. The upper portion of the first card only shall display the engine work areas/zones
and engine illustration. The lower portion shall be divided into horizontal and vertical time graph
columns to program the personnel requirements and the accomplishment of the QECA inspection
requirements. The graph coordinate for time shall be divided into equal vertical increments of one
hour each. Each hourly increment shall be subdivided into five equal parts. EMT shall be
presented in multiples of not less than one-tenth hour.
