The failure rate ($\lambda$) is calculated by modifying a base failure rate ($\lambda_b$) with various factors: $$ \lambda = \lambda_b \times \pi_Q \times \pi_T \times \pi_E \times \pi_S $$
Locate the specific component section in the document, extract λblambda sub b , calculate the factors, and find individual failure rates.
