ED-91A "Lightning Zoning"

We are pleased to announce the publication of ED-91A “Lightning Zoning.”
This ED defines lightning strike zones and provides guidelines for locating them on particular aircraft. The revision incorporates changes throughout that are consistent with in-service reports on aircraft lightning attachment that were collected to support a review of coherence between the zoning established process and the likely and unlikely zones of lightning attachment observed in service.

Available on the EUROCAE website.
