said, throwing his pencil on the table. “Just great. We got a damn hit-and-run.”
    “Hold on, now,” Mike Lee said, in a cool tone. “On behalf of the carrier, I think we have to recognize the flight crew acted responsibly. They have no liability here; but they face possible litigation from the civil aviation authorities in Hong Kong, and they went home to deal with it.”

    “Do, uh, we know who the captain was?” Ron Smith asked timidly.
    “We do,” Mike Lee said. He consulted a leather notebook. “His name is John Chang. Forty-five years old, resident of Hong Kong, six thousand hours’ experience. He’s TransPacific’s senior pilot for the N-22. Very skilled.”
    “Oh yeah?” Burne said, leaning forward across the table. “And when was he last recertified?”
    “Three months ago.”
    “Where?”
    “Right here,” Mike Lee said. “On Norton flight simulators, by Norton instructors.”
    Burne sat back, snorting unhappily.
    “Do we know how he was rated?” Casey asked.
    “Outstanding,” Lee said. “You can check your records.”

Not Human Error (?)
    Marder said to Lee, “Do you think we can get an interview with him, Mike? Will he talk to our service rep at Kaitak?”
    “I’m sure the crew will cooperate,” Lee said. “Especially if you submit written questions … I’m sure I can get them answered within ten days.”
    “Hmm,” Marder said, distressed. “That long …”
    “Unless we get a pilot interview,” Van Trung said, “we may have a problem. The incident occurred one hour prior to landing. The cockpit voice recorder only stores the lasttwenty-five minutes of conversation. So in this case the CVR is useless.”
    “True. But you still have the FDR.”

    “Yes, we have the FDR,” Trung said. But this clearly didn’t assuage his concerns, and Casey knew why. Flight recorders were notoriously unreliable. In the media, they were the mysterious black boxes that revealed all the secrets of a flight. But in reality, they often didn’t work.
    “I’ll do what I can,” Mike Lee promised.
    Casey said, “What do we know about the aircraft?”
    “Aircraft’s brand-new,” Marder said. “Three years’ service. It’s got four thousand hours and nine hundred cycles.”

    “What about inspections?” Doherty asked gloomily. “I suppose we’ll have to wait weeks for the records …”
    “It had a C check in March.”
    “Where?”
    “LAX.”
    “So maintenance was probably good,” Casey said.
    “Correct,” Marder said. “As a first cut, we can’t attribute this to weather, human factors, or maintenance. So we’re in the trenches. Let’s run the fault tree. Did anything about this aircraft cause behavior that looks like turbulence? Structural?”
    “Oh sure,” Doherty said miserably. “A slats deploy would do it. We’ll function hydraulics on all the control surfaces.”
    “Avionics?”
    Trung was scribbling notes. “Right now I’m wondering why the autopilot didn’t override the pilot. Soon as I get the FDR download, I’ll know more.”
    “Electrical?”
    “It’s possible we got a slats deploy from a sneak circuit,” Ron Smith said, shaking his head. “I mean, it’s
possible
 …”
    “Powerplant?”
    “Yeah, powerplant could be involved,” Burne said, running his hand through his red hair. “The thrust reversers could havedeployed in flight. That’d make the plane nose over and roll. But if the reversers deployed, there’ll be residual damage. We’ll check the sleeves.”
    Casey looked down at her pad. She had written:
    Structural — Slats Deploy
    Hydraulics — Slats Deploy
    Avionics — Autopilot
    Electrical — Sneak Circuit
    Powerplant — Thrust Reversers
    That was basically every system on the aircraft.
    “You’ve got a lot of ground to cover,” Marder said, standing and gathering his papers together.
