Spanair accident at Madrid

[fdr]

Birgenair????

Birgenair ALW301: probable Pitot static blockage, suspected to be from mud dauber wasps.

Spanair 5022: ?`

Now if you suggested that AeroPeru 603 was similar (not identical: pitot vs static bloackages) to Birgenair 301....

Now, it is possible for a pitot/static event to occur at any time, not just with wasps nesting or tape applied over static ports, AND a failure would be a high risk factor on a takeoff, and historically such failures tend to be problematic for crews to manage.... one assumes that the DFDR and QAR fitted to this type will ascertain that readily, as it records IAS from the DFDAU, and while GS is not recorded directly, the L/L will provided a derived GS (which is just nice to have to identify quantitatively IAS errors when corrected).

again, common issues are;

• 3rd rock from sun,
• sad

outcome.

Please, await (avidly, if you must) the formal report conducted under Annex 13. If there is something new that is identified as a threat, then one assumes the authorities know their obligations under ICAO, and under EASA and EC law.
