Last week I thought it could be coincidence. An Aserca Airlines DC9 lost cabin preasure during the flight and had to land in Maracaibo. No one was hurt.
About 4 weeks ago the same thing happened on a flight from Porlamar to Caracas. The pilot started a sudden descend and came close to a DC9 from Aeropostal (en route from Caracas to Puerto Ordaz). As the Aeropostal aircraft was equipped with TCAS, the pilot could react and avoid a colission. One passenger on board of the Aeropostal aircaft was hurt.
And here the third incident on an Aserca flight from today: cabin preassure loss en route from Caracas to Puerto Ordaz (sorry, spanish)
This happens on the same day that the mexican authorities ground Aerocalifornia. The Aserca aircraft are the same type (DC9-30) and the same age: around 35-37 years.
And it happens while the FAA is evaluating Venezuela to be upgraded to CAT I . Inspections at Aeropostal and Conviasa maintanace facilities by FAA officials were a great success.
It's time for INAC (the Venezuelan FAA) to check Aserca very closely in order not to loose credibility.....
