What happened
On 16 January 2014, an Airbus A320-214, registration EI-EZV, was involved in an occurrence at London Heathrow Airport. The incident was documented in AAIB Bulletin No 5/2014.
The investigation
During the review of the published investigation materials, a discrepancy was identified regarding the graphical representation of flight parameters. Specifically, the scale used for the 'SIDE STICK PITCH – First Officer' in Figure 1 of the original report contained a labeling error.
Upon investigation of the data, it was determined that the axis labels did not correctly represent the direction of movement. The corrected scale clarifies that positive values exceeding zero represent the side stick being moved forward, while negative values below zero indicate the side stick was moved aft.
Findings
- The error was limited to the labeling of the pitch scale in the flight data plots.
- The underlying analysis of the flight data and the conclusions drawn by the investigators remain unchanged by this correction.
