Read the following scenario, and then use the $$PDCA Process$$ to address the incident involving the accidental activation of the engine fire extinguishers. This systematic approach should help to identify the problem, investigate and identify the root causes, execute a plan to address it$,$ and implement corrective actions to prevent similar incidents, while fostering a culture of continuous improvement and safety within the organization:

"Captain Michael Stevens had been flying for over $20$ years, and today had been one of those days that seemed like it would never end. His long$-$haul flight had been fraught with turbulence, delays, and challenging weather conditions. Now, as he taxied his aircraft to its final parking spot, he was utterly fatigued. The only thing on his mind was completing the shutdown procedures and getting some well$-$deserved rest.

As he powered down the engines and started going through the shutdown checklist, his bleary eyes struggled to focus on the details. One of the last items on the list was arming the engine fire extinguisher. In his exhausted state, he mistakenly triggered the arming sequence for the right engine fire extinguisher.

The extinguisher activated with a deafening hiss, releasing a cloud of fire$-$retardant foam into the engine. Panic washed over Michael as he realized his error. He quickly called the maintenance engineer, Sarah Turner, who had been assigned to the aircraft for routine checks.

Sarah rushed over to the aircraft, her eyes wide with concern. Michael explained what had happened and asked her what to do$.$ Sarah, a competent engineer, was usually well$-$prepared for any situation. However, she had never been trained on this specific procedure. She wasn't immediately sure of the next steps. Her mind raced, and she had to make a decision.

In the aviation industry, safety is paramount. Mistakes can have catastrophic consequences, but it is also crucial to create a culture where people feel safe reporting errors and near misses. This concept was embodied in the idea of a "just culture."

Sarah remembered her training about just culture. It encouraged employees to report errors without fear of punishment when the intent was not malicious or reckless. She knew that both her and Michael's actions would be thoroughly reviewed to understand the root causes and prevent future occurrences.

With a deep breath, Sarah decided what steps to take. She got out the manual and read it$,$ carefully followed each step, and prayed that she wouldn't make things worse. However, in her nervousness, she unintentionally checked and activated the extinguisher for the left engine too.

Foam now sprayed out of the second extinguisher, creating a surreal scene on the tarmac. Passengers in the terminal watched in bewilderment as the aircraft was enveloped in a white, foamy cloud.

Michael and Sarah exchanged looks of disbelief, realizing they had compounded the problem. But in this moment, they understood the importance of a just culture and safety reporting. Instead of covering up the incident, they immediately reported it to their superiors, taking responsibility for their actions."

Create a PDCA Process with this process $-$ Bullet$/$Point form is fine.
