Aircraft Maintenance Tracking Made Simple

Proper maintenance tracking is essential for aircraft safety, regulatory compliance, and resale value. Whether you own an aircraft, manage a fleet, or fly rentals, understanding maintenance tracking is crucial.

Why Maintenance Tracking Matters

Safety First

Maintenance tracking ensures your aircraft is airworthy. Missing an inspection or AD compliance can lead to dangerous situations.

Regulatory Compliance

The FAA requires specific maintenance and inspections. Proper tracking ensures you're compliant and helps during ramp checks or annual inspections.

Financial Protection

Well-documented maintenance increases resale value and can lower insurance premiums. It also helps you budget for upcoming maintenance.

Types of Maintenance Requirements

Time-Based Inspections

Annual Inspection

• Required every 12 calendar months
• Comprehensive inspection by A&P with IA
• Must be completed before expiration

100-Hour Inspection

• Required for aircraft used for hire
• Similar scope to annual
• Can exceed by up to 10 hours if flying to inspection location

Usage-Based Maintenance

Oil Changes

• Typically every 25-50 hours
• Check manufacturer recommendations
• More frequent in dusty environments

Engine Overhaul

• TBO (Time Between Overhaul) varies by engine
• Typically 1,200-2,400 hours
• Can be extended with proper care and monitoring

Calendar-Based Items

ELT Battery

• Replace or recharged when 50% of useful life
• Typically every 24 months

Transponder/Altimeter

• Certification required every 24 calendar months
• Must be done at certified repair station

VOR Check

• Required for IFR every 30 days
• Can be done by pilot
• Must be logged

Airworthiness Directives (ADs)

One-Time ADs

• Must be complied with by specified date
• Permanently recorded

Recurring ADs

• Require periodic inspections or actions
• Must track compliance intervals

Tracking Methods

Paper Systems

Advantages:

• No technology required
• Accepted everywhere
• Simple and straightforward

Disadvantages:

• Easy to lose or damage
• Manual calculations required
• No automatic reminders
• Difficult to share with mechanics

Digital Systems

Popular Apps:

• Savvy Aviation
• Aircraft Maintenance Tracker
• Excel spreadsheets
• Cloud-based databases

Advantages:

• Automatic calculations
• Push notifications for upcoming items
• Cloud backup
• Easy to share
• Historical data analysis

Disadvantages:

• Requires technology
• Subscription costs
• Learning curve

Hybrid Approach (Recommended)

Maintain digital records for convenience but keep paper backups. Store physical logbooks safely and photograph every entry.

Setting Up Your Tracking System

Step 1: Gather All Records

Collect:

• Aircraft logbooks (airframe, engine, propeller)
• AD compliance records
• STCs and 337 forms
• Weight and balance data
• Equipment list

Step 2: Create a Master List

Document current status:

• Total time airframe
• Total time engine
• Time since overhaul (TSO)
• Last annual date
• Last 100-hour (if applicable)
• All recurring AD compliance dates/times

Step 3: Calculate Due Dates

For each item, determine:

• Next due date (calendar)
• Next due time (tach/Hobbs)
• Which comes first
• Lead time for scheduling

Step 4: Set Up Reminders

Create alerts for:

• 60 days before annual
• 30 days before other inspections
• 10 hours before hourly items
• AD compliance deadlines

Sample Tracking Workflow

Pre-Flight

1. Check maintenance status display 2. Verify annual and other inspections are current 3. Review any MEL items or deferred maintenance 4. Check for new ADs

Post-Flight

1. Log flight time 2. Update Hobbs/Tach totals 3. Note any squawks or issues 4. Update "next due" calculations 5. Check if any items are now due

Monthly Review

1. Verify all tracking is current 2. Review upcoming maintenance (next 90 days) 3. Budget for upcoming expenses 4. Check for new ADs 5. Update digital backups

Common Tracking Mistakes

Not Tracking Between Inspections

Don't wait until annual—track continuously.

Ignoring AD Compliance

ADs are legally required. Missing one can ground your aircraft.

Poor Record Keeping

Incomplete records hurt resale value and can cause compliance issues.

No Backup System

Always maintain backup records. Fire, theft, or loss can happen.

Forgetting Calendar Items

Some items are calendar-based regardless of usage.
