Description

On 25 October 2013, a Bombardier CRJ 900 (EC-JYA) being operated by Air Nostrum on a scheduled passenger flight (ANE 8522) from Madrid to San Sebastian made a hard and bounced landing at destination after an approach in day VMC. ATC were unaware of anything abnormal in respect of the landing. After seeing no damage to the aircraft on a post flight inspection, the aircraft commander elected to continue with the next flight back to Madrid, which was uneventful. However, on arrival there, the aircraft was found to be sufficiently damaged by the earlier hard landing to have been unfit for further flight and was grounded.

Investigation

An Investigation was carried out by the Spanish Commission for the Investigation of Civil Aviation Accidents and Incidents (CIAIAC). Recorded data relevant to the Investigation was recovered from the DFDR but relevant data on the CVR had been overwritten. Data from the DFDR was used to confirm that touchdown had occurred at a rate of descent exceeding 600 fpm, which is the [[Aircraft Maintenance Manual|AMM] threshold for an examination of aircraft continued airworthiness.

Following arrival in Madrid, damage to the aircraft found after maintenance were notified of the earlier hard landing by means of the Captain's entry in the Technical Log estimating a hard landing (location unspecified) with a vertical speed of "between 400 and 600 fpm" was documented as:
