This is an erroneous premise which leads to disastrous conclusions. It is not a real quest for safety, it is a false quest for safety. The airlines prefer to blame the Pilots whenever the Pilots fail to survive a crash. While dead, it is very difficult for them to defend themselves, therefore they are usually found to be at fault. The airlines don't want to admit their failures and faults in their practices, procedures, and policies - so they like the Pilots to be blamed, albeit falsely.
This false sense of Pilot fault, or percentage frequency of pilot fault, is what this pretend "quest for safety" is based upon, more fallacy built upon a foundation of fallacy.

JewelStaiteFan, you misunderstood what happened on that fatal flight.

On the night of May 31, 2009, the pilots of Flight 447 did not serve their passengers well.

Unbeknownst to the pilots, ice crystals began to accumulate inside the airplane’s three air-pressure probes, known as pitot tubes, which were mounted on the underside of the nose. The clogging of that particular probe design was a known issue on certain Airbus models, and Air France had decided to replace the probes with ones of an improved design and had sent out an advisory to warn pilots of the problem. The first of the replacement probes had just arrived in Paris and were waiting in a storeroom to be installed.

For Flight 447, it was too late: the probes were quickly clogged. Just after 11:10 P.M., as a result of the blockage, all three of the cockpit’s airspeed indications failed, dropping to impossibly low values. Also as a result of the blockage, the indications of altitude blipped down by an unimportant 360 feet.

So here is the picture at that moment: the airplane was in steady-state cruise, pointing straight ahead without pitching up or down, and with the power set perfectly to deliver a tranquil .80 Mach. The turbulence was so light that one could have walked the aisles—though perhaps a bit unsteadily. Aside from a minor blip in altitude indication, the only significant failure was the indication of airspeed—but the airspeed itself was unaffected. No crisis existed. The episode should have been a non-event, and one that would not last long. The airplane was in the control of the pilots, and if they had done nothing, they would have done all they needed to do.

This paragraph indicates you gave no clue of the concept of INSTRUMENT FLIGHT RULES, or the absolute requirement that the Pilots trust, depend, and believe the Instruments and Indicators. Keeping the newer, better, safer, correct parts stuck in a parts warehouse while the plane takes off with passengers on board is an action severely undermining the system of dependence upon the Instruments.
It is a bureaucratic and beancounting practice taking priority over Safety.
And having the Angle of Attack Indicator removed from the cockpit Instrument cluster is also subjugating Safety.
None of these Reductions in Safe Practices are under control of any Pilots. All of them are the purview of the bureaucratic Practices and Policies of the Corporate level.

But the pilot pulled the stick back. Initially this may have been a startle response to the false indication of a minor altitude loss. But Bonin didn’t just ease the stick back—he hauled it back, three-fourths of the way to the stop, and then he kept on pulling. Alain Bouillard, the French investigator, equated the reaction to curling instinctively into a fetal position. The airplane responded by pitching up into an unsustainable climb, causing its speed to slow and its angle of attack to increase.

Six seconds after Bonin assumed control, with the C-chord altitude alert chiming in the cockpit, a brief stall warning sounded. It was a loud synthetic male voice. It said STALL one time. Robert said, “What was that?” The airplane answered, STALL STALL, and again the C-chord sounded. Neither pilot
