The Federal Aviation Administration (FAA) revealed that it would adopt a new airworthiness directive for 13 U.S.-registered airplanes after reports of "cracking" in the area surrounding the lavatory service panel surfaced. The 13 planes are Boeing 757-200 models.
According to the FAA, there was a high stress concentration in the access panel of the lavatory service panel, the stringer 22 attachment, and the fuselage skin, all of which resulted in "fatigue cracking."
