Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes), and Model A310 series airplanes. This proposed AD was prompted by reports of insufficient clearance for the electrical wiring bundles in the leading and trailing edges of the left and right wings. This proposed AD would require installation of new bracket assemblies to ensure adequate clearance between the wiring and the structure, and installation of protective split sleeves as mechanical protection to the electrical harnesses. We are proposing this AD to detect and correct insufficient clearance of electrical wiring bundles located in the leading and trailing edges of the left and right wings, which could lead to chafing damage and arcing, possibly resulting in an on-board fire.

Airworthiness Directives; Pratt & Whitney Division Turbofan Engines
We are superseding airworthiness directive (AD) 2013-15-09 for all Pratt & Whitney Division (PW) PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 turbofan engine models with certain second-stage high-pressure turbine (HPT) air seals installed. AD 2013- 15-09 required initial and repetitive inspections for cracks in second- stage HPT air seals. This new AD expands the applicability of AD 2013- 15-09 to include additional part numbers (P/Ns), requires removal of the mating hardware if the second-stage HPT air seal is found with a through-crack, and adds a mandatory terminating action. This AD was prompted by reports of cracking in the original location on two additional P/Ns and reports of through-cracks in a new location in the second-stage HPT air seal. We are issuing this AD to prevent failure of the second-stage HPT air seal, which could lead to uncontained engine failure and damage to the airplane.
Amendment of Class E Airspace; Lakeport, CA
This action amends Class E airspace at Lakeport, CA. Controlled airspace is necessary to accommodate Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Lampson Field. The FAA is taking this action to enhance the safety and management of instrument flight rules (IFR) operations at the airport.
