## Probable cause

EXECUTING OF A SIMULATED SINGLE ENGINE APPROACH IN WIND CONDITIONS THAT EXCEEDED THE DEMONSTRATED CROSSWIND CAPABILITY OF THE AIRPLANE WITH BOTH ENGINES OPERATING.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - in flight, go-around (vfr)
  - weather condition - crosswind (contributing factor)
  - go-around - performed, dual student
  - airspeed - not maintained, dual student (cause)
  - remedial action - delayed, pilot in command(cfi) (cause)
  - stall/mush - inadvertent, pilot in command(cfi) (cause)
  - performance data - disregarded, pilot in command(cfi) (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PURPOSE OF THE FLIGHT WAS MULTIENGINE INSTRUCTION. THE STUDENT WAS EXECUTING A SIMULATED RT. ENGINE OUT ILS APPROACH TO RUNWAY 26. THE WIND WAS REPORTED TO BE FORM 360 DEGREES AT 19 KTS. WITH GUSTS TO 24 KTS. THE STUDENT AND INSTRUCTOR ATTEMPTED TO CORRECT FOR THE RIGHT CROSSWIND WITH FULL LEFT AILERON AND RUDDER DEFLECTION. THE AIRPLANE CONTINUED TO DRIFT OFF CENTERLINE AS IT CROSSED THE MIDDLE MARKER. A GO-AROUND WAS ATTEMPTED WITH FULL POWER (BOTH ENGINES) BUT THE AIRSPEED DECAYED AND THE PILOTS COULD NOT MAINTAIN DIRECTIONAL OR ALTITUDE CONTROL. THE PILOT OPERATING HANDBOOK FOR THE BEECH 55 STATES THE DEMONSTRATED CROSSWIND LIMITATION WITH BOTH ENGINES OPERATING IS 22 KTS.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19900508015409A](https://openairdocs.org/incident/19900508015409A), May 8, 1990: Beech 95B55, Denver, CO, Substantial damage. Encountered wind conditions on final. Tried go around but stalled. Crosswind exceeded and too slow.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
