AD/SB tracking statuses, RII catalog structure, FAA Form 337 requirements, and compliance document types.
PlaneConnection tracks maintenance compliance documents across the fleet,
covering Airworthiness Directives (ADs), Service Bulletins (SBs), Required
Inspection Items (RII), FAA Form 337 filings, and other regulatory
compliance records. This page documents the data structures, statuses, and
regulatory requirements for each compliance document type.
Compliance document management requires maintenance_ops:read permission to view and
maintenance_ops:write to create, submit, or modify records. For the regulatory context behind
these requirements, see FAA Part 5 Explained.
Each compliance item carries a status reflecting its current disposition:
Status
API Value
Description
Open
open
Item has been identified as applicable to one or more aircraft but compliance action has not been initiated.
Complied
complied
Compliance action has been completed and documented. Includes the compliance date, method, and reference to the work order or logbook entry.
Recurring
recurring
AD or SB requires repetitive compliance at specified intervals. The system tracks both initial compliance and recurring due dates.
Not Applicable
not_applicable
Item has been reviewed and determined not applicable to the operator’s aircraft (different serial number range, modification status, etc.). Requires documented justification.
14 CFR 135.427 requires Part 135 operators using a continuous airworthiness
maintenance program (CAMP) to designate Required Inspection Items — those
maintenance tasks that, if performed improperly or with incorrect parts,
could result in a failure, malfunction, or defect endangering safe operation.Key requirements under 14 CFR 135.427:
The operator must prepare and maintain a list of RII items
Each RII requires a separate inspection by a person other than the one
who performed the work (14 CFR 135.427(b)(3))
The inspector must hold Required Inspection Authorization (RIA) granted
by the operator
RII items must be reviewed and updated as the fleet composition or
maintenance program changes
An RII inspection must be performed by a person other than the individual who performed the
maintenance work. The inspector must hold a current Required Inspection Authorization from the
operator. PlaneConnection
validates this separation-of-duties requirement during the work order verification step.

Per 14 CFR 43.9(a), the operator must retain one copy of each Form 337 with the aircraft’s
maintenance records. PlaneConnection stores the form data and supports attaching a scanned copy
of the signed original. Record integrity hashing (SHA-384) ensures the digital record has not been
tampered with after entry.
14 CFR 91.417 specifies minimum retention periods for maintenance records:

PlaneConnection retains all compliance documents indefinitely with tamper-evident hash chain
protection. Soft-deleted records are preserved in the database for regulatory compliance. See

the 5-layer integrity system.
