Unplanned Maintenance Drains Profits—What Theme Parks and Airlines Can Teach You

Hidden maintenance costs at a theme park

A few weeks ago, I visited a large theme park in the U.S. While we were queued for the first roller‑coaster of the day, the ride’s control system triggered an alarm and the attraction was temporarily shut down. Hundreds of excited visitors waited for about 25 minutes until a maintenance technician arrived. He simply inserted a key, flicked the master‑reset button, and the ride was back in operation after a brief test run. The crowd erupted in applause as the ride operator declared the attraction open again. As an engineer, I was unimpressed.

Just two hours later, another coaster broke down mid‑ride. The emergency brake engaged and we were suspended for 20 minutes while a maintenance crew opened and closed a loading‑station cover—an outer‑cover interlock had tripped. The ride resumed, the technician smiled, waved, and the crowd cheered once more. In a single seven‑hour visit, I witnessed three breakdowns. I doubt the park will conduct a root‑cause analysis, and I was disappointed to lose over an hour of my day to seemingly trivial repairs.

Unplanned maintenance hurts business

Contrast this with the airline industry. Aircraft are far more complex, yet if they broke down as frequently as theme‑park rides, airlines would collapse. Passengers demand punctuality, and airlines earn revenue only when planes are airborne. The key to reliability is a proactive maintenance philosophy: inspections after every flight and scheduled preventive work keep aircraft in service.

Airlines recognize that maintenance impacts every facet of their operation—customer service, product quality, energy efficiency, and ultimately the bottom line. Regular preventive work eliminates the consequences of failures—delayed flights, compensation payouts, frustrated travelers, and catastrophic events—while maximizing asset availability. Yet many industries still miss the direct link between maintenance and profitability. If a theme park could see how breakdowns cut revenue at the moment tickets are sold, perhaps they would invest more in proactive care.

The maintenance manager is dead. Long live the asset manager!

“We’re too busy for preventive maintenance,” I hear all too often. Yet emergency repairs cost 3–9 times more than planned work. Consider the time and money wasted locating parts, chasing vendors, finding instructions, and prepping the site. By reducing emergency incidents, maintenance costs can drop dramatically, boosting productivity by 50–60%. While emergencies can’t be entirely eliminated, careful planning and scheduling can prevent many of them and slash mean time to repair.

The role of the maintenance manager is evolving. It should be rebranded as the “Asset Manager”—a focus on preserving asset function so business can run smoothly. This shift from firefighting to fire prevention requires strategic planning, data‑driven scheduling, and a commitment to proactive maintenance.
