We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

The FAA proposes to supersede an existing airworthiness directive (AD) for General Electric Company (GE) CF6-50, -80A1/A3, and -80C2A series turbofan engines, installed on Airbus A300 and A310 series airplanes. That AD currently requires initial and repetitive inspections and checks of the thrust reverser actuation systems. This proposed AD would require revised inspection thresholds and intervals, and would require the same actions and additional inspections of the thrust reverser actuation system locking features. This proposed AD results from refined safety analyses performed on the thrust reverser systems by GE and Airbus. We are proposing this AD to prevent inadvertent in-flight thrust reverser deployment, which can result in loss of control of the airplane.

Under this notice, the FAA announces that New York's John F. Kennedy International Airport (JFK) has been designated a Level 3 Coordinated Airport for the summer 2008 scheduling season in accordance with the International Air Transport Association (IATA) Worldwide Scheduling Guidelines. This notice supercedes the September 24, 2007, notice that designated JFK a Level 2 Schedules Facilitated Airport. 72 FR 54317. Based on a recently completed capacity analysis, a review of last summer's demand, the projections for summer 2008, and the agency's decision to seek voluntary schedule reductions from domestic air carriers, the FAA has determined that a Level 3 airport declaration is warranted. The primary coordination constraint is runway/air traffic control capacity. JFK is experiencing increased congestion and delay. Comparing the period of October 2006 through July 2007 to the same period in the previous year, the average daily operations at JFK increased 23 percent; the average daily arrivals with delays greater than one hour increased 114 percent; and on-time gate arrivals within 15 minutes of scheduled time decreased from 69.7 percent to 61.2 percent. The average taxi-out delay increased 19 percent from 30 to almost 36 minutes. On- time departures within 15 minutes of scheduled time declined from 74.7 percent to 65.2 percent. Much of this delay is attributed to volume and is not likely to be entirely mitigated by short-term air traffic control procedural enhancements, airport or airspace efficiency gains, or airport infrastructure changes. For example, from February 2007 through July 2007, JFK's average airport capacity was 81 operations per hour while demand during the busiest hour, 4 p.m., was over 110 scheduled arrivals and departures during summer 2007. Adjacent hours had fewer scheduled flights but still above the average hourly capacity rate. Under a preliminary review of the schedule submissions for summer 2008, the FAA notes that there are proposed schedule increases by domestic carriers and foreign flag carriers. These proposed schedules will result in a significant increase of operations at JFK. While JFK has available capacity for additional flights during some periods of the day, certain hours are currently beyond capacity and would get only worse if the schedules were implemented as proposed. Thus, based on the level of congestion experienced this past summer season, the planned increases for next summer, and the decision to seek voluntary reductions of existing schedules from domestic operators through a scheduling reduction meeting,\1\ an immediate Level 3 designation is warranted.

The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub. L. 101-508) and Part 158 of the Federal Aviation Regulations (14 CFR Part 158). This notice is published pursuant to paragraph (d) of Sec. 158.29.
