N483A

HISTORY OF FLIGHT

On December 13, at 2246 Eastern Standard Time, a Boeing MD-82, N483A, scraped its right wingtip while landing on runway 36 Center at Charlotte Douglas International Airport (CLT), Charlotte, NC. The flight was registered to and operated by American Airlines under the provisions of 14 Code of Federal Regulations Part 121 as a passenger flight. Instrument flight rules (IFR) conditions prevailed for the flight, which operated on an instrument flight rules flight plan. The flight originated at Dallas-Fort Worth International Airport (DFW), Texas at 2035 Eastern Standard Time.

The DFW to CLT leg was flown by the first officer. There were no mechanical issues listed in the logbook of the airplane. The captain reviewed the CLT weather and briefed the first officer on the likelihood of flying a Category III (Cat III)approach upon arrival into CLT.

Departure from DFW was normal, and both pilots ate while discussing the weather in CLT and the fact that the captain would likely be required to conduct the approach based upon American Airlines' policy. American Airlines requires the captain to conduct all Cat III approaches, and when the weather is below 4000' runway visual range or 3/4 mile visibility. At 2130 EST the dispatcher sent flight 1402 the weather and Notices to Airmen. The CLT surface weather observation valid for the arrival time of the flight called for calm winds, visibility of 1/8 statute mile, a 100 foot ceiling, a temperature and dew point of 7 degrees Celsuus, and a barometric pressure of 30.08 inches of mercury. and a deq point of

The crew continued to check the CLT weather, and the captain decided to brief the Cat III approaches to both runway 36R and 36C. The captain said he chose the Cat III approach briefing as a "worst case scenario". According to the first officer, they conducted these briefings referencing several manuals, and completed the briefing several hundred miles from CLT. The first officer also told investigators that the captain briefed him that he expected them to visually pick up the airport early, and he would disconnect the autopilot and land visually.

The captain stated that the last time he had performed a CAT III approach was 9 months previously in the simulator, and had not performed a Cat III approach during line operations in "10-12 years" and "he was a little concerned about it." The first officer stated that he had not flown a Cat III approach in line operations in the last "14-15 years".

Following the briefing, the first officer conducted the descent into CLT. Some time past the SHINE intersection on the arrival to CLT, the flight crew switched pilot flying (PF) duties from the first officer to the captain by switching autopilot and autothrottle controls to the captain. The first officer became the pilot monitoring (PM)and remained so for the rest of the flight.

When the airplane was established on final approach, the first officer said he checked for stable approach criteria and handled ATC communications. He said that ATC was busy launching airplanes and there was a lot of talking on the radio. The captain stated he believed the tower controller was clearing another airplane for takeoff while his flight was inside the outer marker, was concerned about it, but did not query ATC. The last reported visibility received by the flight crew was for an RVR of 1400' for runway 36C. There was no turbulence along the approach, and the crew stated the ride was "smooth" and normal.

The airplane was fully configured prior to arriving at the outer marker with the gear down, speedbrakes armed, and the airspeed about 170 knots. They slowed to approach speed after the outer marker. At about 1000 to 1500 feet on the approach, the first officer noticed a "momentary vibration" of the localizer needle, but there was no movement of the flight controls and no annunciator warnings, and he did not mention the needle movement to the captain. The captain saw the localizer "twitching" just before receiving a landing clearance from the tower at about 600 feet, but it was within limits according to the captain.

As the airplane descended through 300 feet above the ground, the captain began to acquire the runway environment visually, and noticed that the airplane was slightly right of the centerline of the runway with the nose pointed to the left and the airplane drifting toward the left. The captain disconnected the autopilot at that time and began flying the airplane manually. The bank angle aural alert responded as the airplane was being hand flown by the captain. The first officer looked inside the airplane to verify their altitude at about 200 feet, then looked out and noticed the airplane was then left of centerline and maneuvering with "a good amount of bank" to the right. The bank angle aural alert sounded again at about "30-32 feet" while the airplane was in a right correction back to the centerline. The airplane touched down approximately 1000 to 1500 feet down the runway to the left of centerline with the right wing tip coming into contact with the runway surface, and the left main wheels touching down in the grass adjacent to the runway.

At gate arrival, the captain entered "no items" in the maintenance logbook while the first officer began a post flight walk-around of the airplane. During his exterior inspection of the airplane, the first officer noticed minor damage to the right wing tip, right slat and a landing light. He returned to the cockpit and advised the captain. The captain made a logbook entry reflecting the "right wingtip touch" on landing. Neither pilot advised ATC of the incident.

FLIGHT CREW INFORMATION

The captain and first officer had flown together numerous times prior to this pairing. The incident flight was the fourth flight of the day, and occurred on the first day of a four day trip paring.

Both pilots had the proper flying and medical ratings for the incident flight. And, both pilots had successfully completed their last training and proficiency checks. A review of the Accident/Incident Data System and Enforcement Information System revealed no prior accident, incident or enforcement actions for either pilot. On December 14, 2009, the day after the incident, the flight crew was administered a drug and alcohol screening by an American Airlines contract laboratory. According to American Airline's Manager of Flight Safety, both test results for both pilots were negative.

The captain's flight times are as follows:

Total pilot flying time 15,793 hours

Total flying time last 24 hours 7 hours

Total flying time last 30 days 73 hours

Total flying time last 90 days 159 hours

The first officer's flight times are as follows:

Total pilot flying time 11,251 hours

Total flying time last 24 hours 7 hours

Total flying time last 30 days 52 hours

Total flying time last 90 days 188 hours

AIRCRAFT INFORMATION

According to post-incident interviews with investigators, neither pilot observed a failure in the autoflight computer system, the yaw damper system, the pitch control system or the flight director system at the time of the incident. The first officer stated that he successfully performed a Cat III autoland ground test on both sides of the DFGS prior to their departure from DFW to CLT.

Regarding the instrument landing system (ILS) ground transmitters, the CLT Tower Facility log revealed that between the hours of 2100 EST and 2400 EST on December 13, 2009, there were 21 arrivals to runway 36C at CLT. Entries into the log showed no PIREPs (Pilot Reports) or notations indicating anomalies with the ILS for runway 36C at CLT.

Copies of the FAA Technical Performance Records (FAA Form 8750-24 "LOC-Normal Radiated Parameters" and FAA Form 8750-23 "LOC-Normal Ground Check") covering the dates July 21, 2009 to December 18, 2009 for the CLT Runway 36C showed no abnormalities in the signal for the ILS 36C.

A search of the ASRS database covering reports for the CLT airport using "CLT", "CLT.AIPORT", "CLT.TOWER", "CLT.TRACON', and "ILS 36C" as search field criteria yielded no safety reports submitted from January 2005 to February 2010 concerning the ILS 36C at CLT.

ORGANIZATIONAL AND MANAGEMENT INFORMATION

During his post-incident interview, the captain stated that he disconnected the autopilot "sometime below 300 feet," and manually flew the airplane to landing.

American Airlines Airplane Operating Manual, Volume 1, page 40.1, stated that all Cat III approaches are to be flown by the autopilot and to an autoland. In interviews with the MD80 Fleet Training Manager, the MD80 Fleet captain, and an MD80 APD (Aircrew Program Designee), each stated that American Airlines trains its MD80 crews to autoland all Cat III approaches, rather than manually flying the airplane during the final descent to the runway.

Cat III Autoland Restrictions

American Airlines Flight Manual Part 1, Section 10, page 31, 7.1, "Use of Autoland" states, in part that autolands may be conducted to CAT I / II / III designated runways provided that the procedure does not have a chart note or NOTAM which renders the localizer unusable inside the runways threshold. The 11-5A Jeppesen approach chart for the ILS 36C approach to CLT had a note listed on the chart face that stated: IDQG LOC 36C unusable for rollout guidance.

The captain stated in his interview with investigators that he briefed a Cat III approach to both runways 36C and 36R at CLT. Title 14 Code of Federal Regulations (CFR) Part 121.603(a) states, in part that before beginning a flight, each pilot in command shall obtain all available current reports or information on airport conditions and irregularities of navigation facilities that may affect the safety of the flight. After the incident, on December 17, 2009, American Airlines issued an F473 message to append all fl...
