Lightning Strike Aircraft Repair: How Elevate MRO Responds to Emergency Maintenance

‍

When lightning strikes an aircraft mid-flight, the incident demands immediate expert response. At Elevate MRO (part of Elevate Aviation Group), our team specializes in AOG (Aircraft on Ground) emergency repairs, including lightning strike damage assessment and restoration. This case study demonstrates how rapid response, technical expertise, and FAA-compliant procedures returned a partner aircraft to service safely and efficiently.

Understanding Lightning Strike Damage to Aircraft

How Often Do Aircraft Get Hit by Lightning?

Commercial and private aircraft are struck by lightning more frequently than most operators realize:

• Average commercial aircraft: Struck 1-2 times per year
• Business jets: Approximately once every 1,000-3,000 flight hours
• Peak occurrence: During takeoff and landing phases in convective weather

Modern aircraft are engineered with lightning protection systems, including:

• Conductive skin paths that channel electrical current
• Static discharge wicks that dissipate electrical charges
• Bonding and grounding systems throughout the airframe
• Lightning-resistant materials in critical components

However, even with these protections, lightning strike damage to aircraft can occur and requires thorough inspection and repair before return to service.

Case Study: Emergency Windshield Replacement After Lightning Strike

The Incident: Mid-Flight Lightning Strike

Aircraft Type: [Business jet - specific model if appropriate]
Location: En route during convective weather conditions
Impact Point: Windshield and forward fuselage area
Immediate Result: Aircraft diverted for emergency inspection

The pilot reported a bright flash and loud noise characteristic of a lightning strike. Following standard procedures, the crew declared the situation and diverted to the nearest suitable airport where Elevate MRO facilities could provide immediate assessment.

Initial Lightning Strike Damage Assessment

Upon arrival, Elevate MRO's AOG response team conducted a comprehensive lightning strike inspection per FAA Advisory Circular AC 43.13-1B and aircraft-specific maintenance manual requirements:

Primary Damage Identified:

• Windshield: Significant impact damage with compromised structural integrity requiring immediate replacement
• Static discharge wicks: Multiple wicks damaged or destroyed from electrical discharge (common lightning strike damage)
• Wing sealant: Compromised sealant along wing surfaces where electrical current traveled through airframe

Secondary Inspection Areas:

• Radome and nose cone (checked for entry point damage)
• Wing tips and trailing edges (common exit points)
• Avionics systems (tested for electrical interference or damage)
• Fuel system components (inspected per lightning strike protocols)
• Flight control surfaces (checked for burn marks or structural damage)

Emergency Aircraft Windshield Replacement Process

With damage confirmed and parts sourced, Elevate MRO's certified technicians began the windshield replacement following OEM specifications:

Step 1: Damaged Windshield Removal

• Cabin depressurization and electrical system isolation
• Careful removal of damaged windshield panels
• Inspection of windshield frame and surrounding structure
• Documentation with photography for insurance and records

Step 2: Frame Preparation and Inspection

• Thorough cleaning of windshield frame surfaces
• Inspection for hidden cracks or stress damage
• Measurement verification to ensure frame integrity
• Application of corrosion prevention treatments

Step 3: OEM Windshield Installation

• New OEM windshield installed per manufacturer specifications
• Premium aerospace sealant application (ensuring pressure integrity)
• Torque-specific fastener installation with calibrated tools
• Multi-stage curing process for optimal seal performance

Step 4: System Testing and Validation

• Pressure leak testing to verify cabin seal integrity
• Windshield heating system functional check
• Electrical bonding verification
• Visual inspection under various lighting conditions

Static Wick Replacement and Wing Seal Restoration

Lightning strikes commonly damage static discharge wicks—the small rod-like devices on wing tips and control surfaces that dissipate static electricity:

Static Wick Repair Process:

• Removal of all damaged static wicks
• Inspection of mounting points for corrosion or damage
• Installation of OEM replacement wicks with proper torque values
• Electrical continuity testing to ensure proper grounding

Wing Sealant Repair:

• Removal of damaged or compromised sealant
• Surface preparation and cleaning
• Application of FAA-approved aviation sealant
• Curing period before return to service

Comprehensive Post-Repair Inspection

Before releasing the aircraft, Elevate MRO conducted:

• Complete functional testing of all affected systems
• Detailed logbook entries documenting repairs per FAA requirements
• Structural integrity verification ensuring no hidden damage remained
• Test flight coordination (if required based on repair scope)

Result: Aircraft returned to service in minimal time with full FAA compliance and complete documentation for owner and insurance records.

Why Lightning Strike Aircraft Repair Requires Specialized Expertise

FAA Compliance and Regulatory Requirements

Lightning strike repairs must comply with:

• FAA Advisory Circular AC 43.13-1B Chapter 11: Lightning strike damage assessment and repair procedures
• Aircraft-specific maintenance manuals: OEM requirements for inspection and repair
• 14 CFR Part 43: Maintenance, preventive maintenance, rebuilding, and alteration standards
• Type certificate data sheets: Approved materials and methods

Elevate MRO maintains all necessary certifications and technical data to perform these repairs in accordance with regulatory requirements.

Critical Safety Considerations

Improper lightning strike repairs can create serious safety risks:

• Windshield failure: Compromised windshields can fail during pressurization or flight loads
• Electrical system damage: Hidden avionics or wiring damage may cause in-flight failures
• Structural weakening: Lightning can cause micro-cracks that propagate over time
• Fuel system hazards: Electrical damage near fuel systems requires careful inspection

Elevate MRO's approach prioritizes thorough inspection over quick turnaround—ensuring no damage is overlooked and all repairs meet or exceed safety standards.

Frequently Asked Questions About Lightning Strike Aircraft Damage

Is it safe to fly after a lightning strike?
Not until a thorough inspection is completed by certified technicians. Even if no damage is visible, hidden electrical or structural damage may exist that poses safety risks.

How long does lightning strike aircraft repair take?
Timeline depends on damage extent. Windshield replacement and static wick repairs typically require 2-5 days including inspection, parts sourcing, repair, and testing. Complex repairs may take longer.

Does insurance cover lightning strike damage?
Most aircraft insurance policies cover lightning strike damage as a covered peril. Elevate MRO provides detailed documentation to support insurance claims.

What are static discharge wicks and why do they matter?
Static wicks dissipate electrical charges that build up during flight. Damaged wicks can lead to radio interference, navigation system issues, and increased vulnerability to future lightning strikes.

Can I fly to a maintenance facility after a lightning strike?
Only if a qualified inspector determines the aircraft is airworthy. In many cases, immediate repair is required before the aircraft can safely fly.

How can I prevent lightning strike damage?
While strikes can't be entirely prevented, avoiding convective weather, maintaining lightning protection systems, and following weather avoidance procedures reduce risk.
