HASK172-147 Forward Doorpost Reinforcement Service Kit
Alternative to Cessna SK172-147
Strengthen a known structural stress point on select Cessna aircraft with the HASK172-147 forward doorpost reinforcement kit. This kit is engineered as a direct alternative to the OEM Cessna SK172-147 service kit, designed to support compliance with FAA Airworthiness Directive AD 2020-18-01. It reinforces the lower forward cabin doorpost and strut-attach bulkhead area (the region where fatigue cracking has been documented across the fleet).
Refer to Service Bulletin SEB95-19 and SEB93-5, and AD 2020-18-01.
Features:
- Cost-effective alternative to the OEM SK172-147
- Functionally equivalent reinforcement for AD compliance
- Installed per Cessna SEB95-19 / SEB93-5R1
Purpose:
Reinforces the lower forward doorpost bulkhead, strengthens the wing-strut attach area, and helps mitigate fatigue cracking in a high-load structural zone, supporting long-term airworthiness and continued safe operation.
