Make Records & Research A Priority In Your Maintenance Event

December 2025

At Duncan Aviation, we strongly recommend that when planning a maintenance event, you include detailed records research as part of your maintenance service package. This approach goes a long way to ensure compliance, safety, and managing long-term costs.

Uncovering Missing Requirements

Detailed records often uncover mandatory ongoing inspections tied to STCs (Supplemental Type Certificates) that must be performed and properly documented.

It’s not the major maintenance and inspections that typically get missed, but rather the small, unknown programs and non-OEM-related equipment. Over the last several years, our review of various aircraft logbooks has consistently identified missing entries for these critical items.

Common STC-Related Items Requiring Ongoing Inspections:

  • Portable fire bottles
  • Smoke detectors and smoke hoods
  • Heater drain mast checks
  • antenna doubler inspections
  • Defibrillator inspections and medical kits
  • Batteries
  • Water treatment and water filters

Overlooking Non-Standard Events

A detailed review of the records may help uncover inspections that do not coincide with normal Chapter 5 hourly, cyclical, and calendar events. These non-standard events are easily overlooked in routine planning:

  • Serialized Chapter 5 inspections
  • Airworthiness Directives
  • Nondestructive testing events

The Cost Of Life-Limited Parts

Detailed records are critically important during major inspections, such as a landing gear overhaul or inspection. Identifying the many life-limited components within the gear is crucial.

Determining the exact status of installed components is required to identify how much life is remaining. If a component's history is not properly documented in your records, the part has an unknown status, which typically results in:

  • Mandatory replacement of the component.
  • Significant, unnecessary cost and downtime for your aircraft.

The Duncan Aviation Advantage

Anything that affects an aircraft must be documented in a maintenance entry. Duncan Aviation is one of a few MRO (Maintenance, Repair, and Overhaul) companies that can provide customers with a comprehensive package that includes tip-to-tail aircraft maintenance services, thorough records research, and maintenance tracking through the Duncan Tracker services.
