Maintenance Record (OPNAV 4790/38) (fig.
4-17) is used so that scheduled work can be
assigned in a preplanned manner between
calendar/phased inspections. The certification by
maintenance personnel of performance of the
preflight, turnaround, post flight, and daily
inspections is made on this form. These records
may be destroyed upon completion of the next
like inspection. All other inspections are recorded
on the VIDS/MAF.
Sequence Control Charts/Cards (SCCs)
Sequence control charts/cards (SCCs) are
graphic, sequential work displays. They are
prepared to ensure the orderly planning and timely
performance of aircraft and engine maintenance
requirements. The SCCs integrate all required
periodic maintenance work to effectively reduce
the total out-of-service time required for a
complete scheduled maintenance job.
Maintenance personnel of aircraft that come
under the phased PMS are provided with 5- by
8-inch SCCs that serve the same purpose of the
larger SCCs that are used with aircraft under the
calendar inspection concept. When the Even and
Odd calendar inspection concept is used, SCCs
titled Calendar Even and Calendar Odd are
provided to maintenance personnel.
The checklist format for inspections provides
maintenance personnel with abbreviated require-
ments for turnaround and preoperational
When checklists are used, the
inspection requirements are consecutively
numbered and arranged in a logical working
