## Summary

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 747-8 and 747-8F series airplanes. This proposed AD was prompted by reports of damaged vapor seals, block seals, and heat shield seals on the outboard pylons between the engine strut and aft fairing. This proposed AD would require installing new aft fairing vapor seals, heatshield seals, heatshield seal retainers, block seals and outboard lateral restraint access panels. We are proposing this AD to address the unsafe condition on these products.
