c212-100 this isn't the military. Passengers including family members pay fares and get on an aircraft expecting everything possible to be have been done to ensure risk is kept at a minimum.
Again, assuming no tampering, which I really do doubt as that could most definitely result in severe legal proceedings, TAP, their pilots or whoever have not kept their side of the bargain. The reasons are irrelevant.
M.A.201 Responsibilities
(a) The owner is responsible for the continuing airworthiness of an aircraft and shall ensure that no flight takes place
unless:
1. the aircraft is maintained in an airworthy condition, and;
2. any operational and emergency equipment fitted is correctly installed and serviceable or clearly identified as
unserviceable, and;
3. the airworthiness certificate remains valid, and;
4. the maintenance of the aircraft is performed in accordance with the approved maintenance programme as specified
in M.A.302.
This rule was broken.
M.A.301 Continuing airworthiness tasks
The aircraft continuing airworthiness and the serviceability of both operational and emergency equipment shall be
ensured by:
1. the accomplishment of pre-flight inspections;
2. the rectification to an officially recognised standard of any defect and damage affecting safe operation taking into
account, for all large aircraft or aircraft used for commercial air transport, the minimum equipment list and configuration
deviation list if applicable to the aircraft type;
3. the accomplishment of all maintenance, in accordance with the M.A.302 approved aircraft maintenance programme;
4. for all large aircraft or aircraft used for commercial air transport the analysis of the effectiveness of the M.A.302
approved maintenance programme;
5. the accomplishment of any applicable:
(i) airworthiness directive,
(ii) operational directive with a continuing airworthiness impact,
(iii) continued airworthiness requirement established by the Agency,
(iv) measures mandated by the competent authority in immediate reaction to a safety problem;
6. the accomplishment of modifications and repairs in accordance with M.A.304;
7. for non-mandatory modifications and/or inspections, for all large aircraft or aircraft used for commercial air transport
the establishment of an embodiment policy;
8. maintenance check flights when necessary.
This rule was broken
M.A.306 Operator's technical log system
(a) In the case of commercial air transport, in addition to the requirements of M.A.305, an operator shall use an aircraft
technical log system containing the following information for each aircraft:
1. information about each flight, necessary to ensure continued flight safety, and;
2. the current aircraft certificate of release to service, and;
3. the current maintenance statement giving the aircraft maintenance status of what scheduled and out of phase
maintenance is next due except that the competent authority may agree to the maintenance statement being kept
elsewhere, and;
4. all outstanding deferred defects rectifications that affect the operation of the aircraft, and;
5. any necessary guidance instructions on maintenance support arrangements.
(b) The aircraft technical log system and any subsequent amendment shall be approved by the competent authority.
(c) An operator shall ensure that the aircraft technical log is retained for 36 months after the date of the last entry.
This rule was broken
M.A.403 Aircraft defects
(a) Any aircraft defect that hazards seriously the flight safety shall be rectified before further flight.
(b) Only the authorised certifying staff, according to M.A.801(b)1, M.A.801(b)2 or Part-145 can decide, using M.A.401
maintenance data, whether an aircraft defect hazards seriously the flight safety and therefore decide when and which
rectification action shall be taken before further flight and which defect rectification can be deferred. However, this
does not apply when:
1. the approved minimum equipment list as mandated by the competent authority is used by the pilot; or,
2. aircraft defects are defined as being acceptable by the competent authority.
(c) Any aircraft defect that would not hazard seriously the flight safety shall be rectified as soon as practicable, after the
date the aircraft defect was first identified and within any limits specified in the maintenance data.
(d) Any defect not rectified before flight shall be recorded in the M.A.305 aircraft maintenance record system or
M.A.306 operator's technical log system as applicable.
