“How do you know that?”
“My father taught me. A damaged fuel path can destroy an engine from the inside, slowly.”
For a long moment Richard said nothing.
Then he made the most unexpected decision of his life.
“What’s your name?”
“Grace Johnson.”
“Grace,” he said, “come with me.”
She followed him through the airport, terrified.
People stared, wrinkled their noses, whispered. Security tried to stop her, but Richard silenced them instantly.
Inside the maintenance hangar, twenty engineers stopped working when they saw their billionaire boss walk in with a homeless woman.
“Sir,” the chief engineer asked, stunned, “what is this?”
“This is Grace,” Richard said. “Bring me engine number seven. Let her examine it.”
The protest came immediately.
“Sir, this is ridiculous—”
“I said now.”
The parts were brought out.
Grace stepped forward, trembling, and asked for a magnifying glass. One engineer handed it to her with a mocking smile.
She ignored him.
She held the fuel injector up to the light and studied it carefully.
Then she looked at Richard.
“Sir,” she said quietly, “there are scratches inside. Very tiny. But enough to distort the fuel spray.”
The chief engineer snatched the injector from her hand and looked for himself.
The smirk vanished from his face.
His skin went pale.
“Oh my God,” he whispered. “She’s right.”
One by one, the others rushed over.
All of them found the same thing.
Richard’s voice cut across the room.
“Check every injector from every failed engine. Now.”
For three hours the hangar erupted into frantic motion.
Every damaged engine had the same problem.
All the injectors were scratched inside.
The chief engineer looked ready to collapse.
“We were looking at the big systems,” he said hoarsely. “The turbines, the chambers, the electronics… We never thought to inspect the injector interiors with magnification.”
Richard turned slowly toward Grace.
“What causes scratches like these?”
She answered without hesitation.
“Dirty fuel. If contaminated fuel carries tiny particles of metal or grit, they scrape the injector walls little by little. It happens slowly over months. Eventually the spray pattern changes, combustion goes wrong, and the engine starts knocking.”
The chief engineer’s face changed.
“Sir… six months ago we changed to a cheaper fuel supplier.”
Richard’s expression hardened.
“You’re telling me we destroyed our own engines to save money on fuel?”
No one answered.
Richard began to laugh—a harsh, disbelieving laugh.
“Three billion naira,” he said. “Three billion. And a homeless woman solved it in five minutes.”
He immediately called the injector manufacturer.
“I need five hundred new injectors. I don’t care what it costs. I need them now.”
Then he called the fuel supplier and fired them on the spot.
Then he hired the best fuel company in the country and ordered daily purity tests.
Finally, he turned to Grace.
