Which step is part of deferring an aircraft discrepancy?

• A. Complete form DMI
• B. Email a photo of both the 86-100 and the DMI to Maintenance department
• C. Record the discrepancy on 86-100 Form
• D. Place placards

Answer: (C)

Deferring a discrepancy means you acknowledge a fault but allow the flight to proceed under defined limitations while arranging for later repair. The essential part of that process is creating a formal, auditable record of the discrepancy and its deferral. Recording the discrepancy on the 86-100 Form provides the official deferral record, capturing what’s wrong, any applicable operational limits, and the plan and timeline for corrective action. This ensures the crew, maintenance control, and management have a shared, traceable understanding of what is deferred and when it must be addressed, which is required by maintenance procedures and regulatory expectations.

Other actions listed aren’t the formal deferral record. Completing a different form, emailing photos, or placing placards may occur in various workflows or situational contexts, but they do not substitute for the official 86-100 deferral documentation needed to authorize and track the deferred item.
