When reading this, is anyone else getting a booking.com advert for "926 properties in Dubai. Search now".
FYI FAR 25.561b (Crashworthiness) requires
"For equipment, cargo in the passenger compartments and any other large masses, the following apply:
(1) Except as provided in paragraph(c)(2) of this section, these items must be positioned so that if they break loose, they will be unlikely to:
(i) Cause direct injury to occupants;
(ii) Penetrate fuel tanks or lines or cause fire or explosion hazard by damage to adjacent systems; or
(iii) Nullify any of the escape facilities provided for use after an emergency landing."
Applies to wing mounted engines and is usually met by fuse links in conjunction with a range of break-away scenarios.
