(E) Autoland not installed on this aircraft.

(P) Something loose in cockpit.

(E) Something tightened in cockpit.

(P) Evidence of leak on right main landing gear.

(E) Evidence removed.

(P) Autopilot in altitude hold mode produces a 200 fpm descent.

(E) Cannot reproduce problems on ground.

Definition

  • “Flight Data Monitoring (FDM ) is the systematic, pro-active use of digital data from routine operations to improve aviation safety within an intrinsically non-punitive and just culture”*

  • CAA UK CAP 739, edition 2, 2013



Case study 2
Case Study #2

ERAU

Aviation Safety Department

  • Solo XC dispatched late morning

  • DAB – GNV – XFL – DAB

  • Skipped XFL during return leg

  • Two landing attempts on Runway 16 at DAB

    • First try – go around

    • Second try – prop and wingtip strike


Facts
Facts

ERAU

Student was uninjured

Airplane sustained damage only to propeller

No property damage

Airplane did not depart paved runway surface

Student properly certificated and endorsed

Airplane properly certificated, inspected, and airworthy with no defects

Wind was 090 at 11 during incident landing

Runway 7L-25R was closed

  • Both approaches were stabilized with proper crab angle

  • First landing try was premature, flat, right of centerline, bounced, resulted in go around

  • Second landing try was also flat farther right of centerline with the following attitude:

    • Pitch – 0.77 degree nose up

    • Roll – 4.2 degrees right

    • Yaw – 20.6 degrees left

  • The touchdown created a large side load on the right side

  • Side load caused the airplane to roll right and pitch down

  • Prop strike occurred with following attitude:

    • Pitch – 15.16 degrees nose down

    • Roll – 22.26 degrees right

    • Yaw – 24.3 degrees left

  • Prop strike lasted for about 1 second

  • Control was regained before edge of runway

Findings
Findings

ERAU

Aviation Safety Department

  • Improper crosswind correction

    • Left rudder and right aileron was applied, the opposite would have been correct

  • Large side load and lack of back pressure made situation worse

  • Crosswind exceeded student’s capability

Case #2 -Unauthorized Maneuvers

ERAU

  • Data found upon regular analysis

    • ExceedenceType: MAX_RPM

    • Begin Time: 9/16/2011

    • End Time: 9/16/2011

    • Threshold: 2700

    • Maximum exceedence value: 2760

    • Exceedence Type: VNE

    • Begin Time: 9/16/2011

    • End Time: 9/16/2011

    • Threshold: 158

    • Maximum exceedence value: 159.21


Findings1
Findings

ERAU

Aviation Safety Department

Student attempted a roll of the C172 on his first unsupervised solo

Student was shaken and did not down the aircraft

The only recorded parameter that was exceeded was RPM

Student did not tell anyone of the instance





Cast a bigger tighter net beyond exceedance
Cast a Bigger Tighter Net: Beyond Exceedance

Event Sets

  • Capture more than limitations, capture the “IF this and this or that happens”

  • Example: if the AC is <500 AGL and FPM < -1000 for 3 secondsTriggered event
